Struct collections::vec::Vec 1.0.0
[−]
[src]
pub struct Vec<T> { /* fields omitted */ }
A contiguous growable array type, written Vec<T>
but pronounced 'vector'.
Examples
let mut vec = Vec::new(); vec.push(1); vec.push(2); assert_eq!(vec.len(), 2); assert_eq!(vec[0], 1); assert_eq!(vec.pop(), Some(2)); assert_eq!(vec.len(), 1); vec[0] = 7; assert_eq!(vec[0], 7); vec.extend([1, 2, 3].iter().cloned()); for x in &vec { println!("{}", x); } assert_eq!(vec, [7, 1, 2, 3]);Run
The vec!
macro is provided to make initialization more convenient:
let mut vec = vec![1, 2, 3]; vec.push(4); assert_eq!(vec, [1, 2, 3, 4]);Run
It can also initialize each element of a Vec<T>
with a given value:
let vec = vec![0; 5]; assert_eq!(vec, [0, 0, 0, 0, 0]);Run
Use a Vec<T>
as an efficient stack:
let mut stack = Vec::new(); stack.push(1); stack.push(2); stack.push(3); while let Some(top) = stack.pop() { // Prints 3, 2, 1 println!("{}", top); }Run
Indexing
The Vec
type allows to access values by index, because it implements the
Index
trait. An example will be more explicit:
let v = vec![0, 2, 4, 6]; println!("{}", v[1]); // it will display '2'Run
However be careful: if you try to access an index which isn't in the Vec
,
your software will panic! You cannot do this:
let v = vec![0, 2, 4, 6]; println!("{}", v[6]); // it will panic!Run
In conclusion: always check if the index you want to get really exists before doing it.
Slicing
A Vec
can be mutable. Slices, on the other hand, are read-only objects.
To get a slice, use &
. Example:
fn read_slice(slice: &[usize]) { // ... } let v = vec![0, 1]; read_slice(&v); // ... and that's all! // you can also do it like this: let x : &[usize] = &v;Run
In Rust, it's more common to pass slices as arguments rather than vectors
when you just want to provide a read access. The same goes for String
and
&str
.
Capacity and reallocation
The capacity of a vector is the amount of space allocated for any future elements that will be added onto the vector. This is not to be confused with the length of a vector, which specifies the number of actual elements within the vector. If a vector's length exceeds its capacity, its capacity will automatically be increased, but its elements will have to be reallocated.
For example, a vector with capacity 10 and length 0 would be an empty vector
with space for 10 more elements. Pushing 10 or fewer elements onto the
vector will not change its capacity or cause reallocation to occur. However,
if the vector's length is increased to 11, it will have to reallocate, which
can be slow. For this reason, it is recommended to use Vec::with_capacity
whenever possible to specify how big the vector is expected to get.
Guarantees
Due to its incredibly fundamental nature, Vec
makes a lot of guarantees
about its design. This ensures that it's as low-overhead as possible in
the general case, and can be correctly manipulated in primitive ways
by unsafe code. Note that these guarantees refer to an unqualified Vec<T>
.
If additional type parameters are added (e.g. to support custom allocators),
overriding their defaults may change the behavior.
Most fundamentally, Vec
is and always will be a (pointer, capacity, length)
triplet. No more, no less. The order of these fields is completely
unspecified, and you should use the appropriate methods to modify these.
The pointer will never be null, so this type is null-pointer-optimized.
However, the pointer may not actually point to allocated memory. In particular,
if you construct a Vec
with capacity 0 via Vec::new()
, vec![]
,
Vec::with_capacity(0)
, or by calling shrink_to_fit()
on an empty Vec, it will not allocate memory. Similarly, if you store zero-sized
types inside a Vec
, it will not allocate space for them. Note that in this case
the Vec
may not report a capacity()
of 0. Vec
will allocate if and only
if mem::size_of::<T>()
* capacity() > 0
. In general, Vec
's allocation
details are subtle enough that it is strongly recommended that you only
free memory allocated by a Vec
by creating a new Vec
and dropping it.
If a Vec
has allocated memory, then the memory it points to is on the heap
(as defined by the allocator Rust is configured to use by default), and its
pointer points to len()
initialized elements in order (what you would see
if you coerced it to a slice), followed by capacity()
-
len()
logically uninitialized elements.
Vec
will never perform a "small optimization" where elements are actually
stored on the stack for two reasons:
It would make it more difficult for unsafe code to correctly manipulate a
Vec
. The contents of aVec
wouldn't have a stable address if it were only moved, and it would be more difficult to determine if aVec
had actually allocated memory.It would penalize the general case, incurring an additional branch on every access.
Vec
will never automatically shrink itself, even if completely empty. This
ensures no unnecessary allocations or deallocations occur. Emptying a Vec
and then filling it back up to the same len()
should incur no calls to
the allocator. If you wish to free up unused memory, use
shrink_to_fit
.
push
and insert
will never (re)allocate if the reported capacity is
sufficient. push
and insert
will (re)allocate if
len()
==
capacity()
. That is, the reported capacity is completely
accurate, and can be relied on. It can even be used to manually free the memory
allocated by a Vec
if desired. Bulk insertion methods may reallocate, even
when not necessary.
Vec
does not guarantee any particular growth strategy when reallocating
when full, nor when reserve
is called. The current strategy is basic
and it may prove desirable to use a non-constant growth factor. Whatever
strategy is used will of course guarantee O(1)
amortized push
.
vec![x; n]
, vec![a, b, c, d]
, and
Vec::with_capacity(n)
, will all produce a Vec
with exactly the requested capacity. If len()
==
capacity()
,
(as is the case for the vec!
macro), then a Vec<T>
can be converted to
and from a Box<[T]>
without reallocating or moving the elements.
Vec
will not specifically overwrite any data that is removed from it,
but also won't specifically preserve it. Its uninitialized memory is
scratch space that it may use however it wants. It will generally just do
whatever is most efficient or otherwise easy to implement. Do not rely on
removed data to be erased for security purposes. Even if you drop a Vec
, its
buffer may simply be reused by another Vec
. Even if you zero a Vec
's memory
first, that may not actually happen because the optimizer does not consider
this a side-effect that must be preserved.
Vec
does not currently guarantee the order in which elements are dropped
(the order has changed in the past, and may change again).
Methods
impl<T> Vec<T>
[src]
fn new() -> Vec<T>
Constructs a new, empty Vec<T>
.
The vector will not allocate until elements are pushed onto it.
Examples
let mut vec: Vec<i32> = Vec::new();Run
fn with_capacity(capacity: usize) -> Vec<T>
Constructs a new, empty Vec<T>
with the specified capacity.
The vector will be able to hold exactly capacity
elements without
reallocating. If capacity
is 0, the vector will not allocate.
It is important to note that this function does not specify the length of the returned vector, but only the capacity. For an explanation of the difference between length and capacity, see Capacity and reallocation.
Examples
let mut vec = Vec::with_capacity(10); // The vector contains no items, even though it has capacity for more assert_eq!(vec.len(), 0); // These are all done without reallocating... for i in 0..10 { vec.push(i); } // ...but this may make the vector reallocate vec.push(11);Run
unsafe fn from_raw_parts(ptr: *mut T, length: usize, capacity: usize) -> Vec<T>
Creates a Vec<T>
directly from the raw components of another vector.
Safety
This is highly unsafe, due to the number of invariants that aren't checked:
ptr
needs to have been previously allocated viaString
/Vec<T>
(at least, it's highly likely to be incorrect if it wasn't).length
needs to be less than or equal tocapacity
.capacity
needs to be the capacity that the pointer was allocated with.
Violating these may cause problems like corrupting the allocator's internal datastructures.
The ownership of ptr
is effectively transferred to the
Vec<T>
which may then deallocate, reallocate or change the
contents of memory pointed to by the pointer at will. Ensure
that nothing else uses the pointer after calling this
function.
Examples
use std::ptr; use std::mem; fn main() { let mut v = vec![1, 2, 3]; // Pull out the various important pieces of information about `v` let p = v.as_mut_ptr(); let len = v.len(); let cap = v.capacity(); unsafe { // Cast `v` into the void: no destructor run, so we are in // complete control of the allocation to which `p` points. mem::forget(v); // Overwrite memory with 4, 5, 6 for i in 0..len as isize { ptr::write(p.offset(i), 4 + i); } // Put everything back together into a Vec let rebuilt = Vec::from_raw_parts(p, len, cap); assert_eq!(rebuilt, [4, 5, 6]); } }Run
fn capacity(&self) -> usize
Returns the number of elements the vector can hold without reallocating.
Examples
let vec: Vec<i32> = Vec::with_capacity(10); assert_eq!(vec.capacity(), 10);Run
fn reserve(&mut self, additional: usize)
Reserves capacity for at least additional
more elements to be inserted
in the given Vec<T>
. The collection may reserve more space to avoid
frequent reallocations.
Panics
Panics if the new capacity overflows usize
.
Examples
let mut vec = vec![1]; vec.reserve(10); assert!(vec.capacity() >= 11);Run
fn reserve_exact(&mut self, additional: usize)
Reserves the minimum capacity for exactly additional
more elements to
be inserted in the given Vec<T>
. Does nothing if the capacity is already
sufficient.
Note that the allocator may give the collection more space than it
requests. Therefore capacity can not be relied upon to be precisely
minimal. Prefer reserve
if future insertions are expected.
Panics
Panics if the new capacity overflows usize
.
Examples
let mut vec = vec![1]; vec.reserve_exact(10); assert!(vec.capacity() >= 11);Run
fn shrink_to_fit(&mut self)
Shrinks the capacity of the vector as much as possible.
It will drop down as close as possible to the length but the allocator may still inform the vector that there is space for a few more elements.
Examples
let mut vec = Vec::with_capacity(10); vec.extend([1, 2, 3].iter().cloned()); assert_eq!(vec.capacity(), 10); vec.shrink_to_fit(); assert!(vec.capacity() >= 3);Run
fn into_boxed_slice(self) -> Box<[T]>
Converts the vector into Box<[T]>
.
Note that this will drop any excess capacity. Calling this and
converting back to a vector with into_vec()
is equivalent to calling
shrink_to_fit()
.
Examples
let v = vec![1, 2, 3]; let slice = v.into_boxed_slice();Run
Any excess capacity is removed:
let mut vec = Vec::with_capacity(10); vec.extend([1, 2, 3].iter().cloned()); assert_eq!(vec.capacity(), 10); let slice = vec.into_boxed_slice(); assert_eq!(slice.into_vec().capacity(), 3);Run
fn truncate(&mut self, len: usize)
Shortens the vector, keeping the first len
elements and dropping
the rest.
If len
is greater than the vector's current length, this has no
effect.
The drain
method can emulate truncate
, but causes the excess
elements to be returned instead of dropped.
Examples
Truncating a five element vector to two elements:
let mut vec = vec![1, 2, 3, 4, 5]; vec.truncate(2); assert_eq!(vec, [1, 2]);Run
No truncation occurs when len
is greater than the vector's current
length:
let mut vec = vec![1, 2, 3]; vec.truncate(8); assert_eq!(vec, [1, 2, 3]);Run
Truncating when len == 0
is equivalent to calling the clear
method.
let mut vec = vec![1, 2, 3]; vec.truncate(0); assert_eq!(vec, []);Run
fn as_slice(&self) -> &[T]
1.7.0
Extracts a slice containing the entire vector.
Equivalent to &s[..]
.
Examples
use std::io::{self, Write}; let buffer = vec![1, 2, 3, 5, 8]; io::sink().write(buffer.as_slice()).unwrap();Run
fn as_mut_slice(&mut self) -> &mut [T]
1.7.0
Extracts a mutable slice of the entire vector.
Equivalent to &mut s[..]
.
Examples
use std::io::{self, Read}; let mut buffer = vec![0; 3]; io::repeat(0b101).read_exact(buffer.as_mut_slice()).unwrap();Run
unsafe fn set_len(&mut self, len: usize)
Sets the length of a vector.
This will explicitly set the size of the vector, without actually modifying its buffers, so it is up to the caller to ensure that the vector is actually the specified size.
Examples
use std::ptr; let mut vec = vec!['r', 'u', 's', 't']; unsafe { ptr::drop_in_place(&mut vec[3]); vec.set_len(3); } assert_eq!(vec, ['r', 'u', 's']);Run
In this example, there is a memory leak since the memory locations
owned by the inner vectors were not freed prior to the set_len
call:
let mut vec = vec![vec![1, 0, 0], vec![0, 1, 0], vec![0, 0, 1]]; unsafe { vec.set_len(0); }Run
In this example, the vector gets expanded from zero to four items without any memory allocations occurring, resulting in vector values of unallocated memory:
let mut vec: Vec<char> = Vec::new(); unsafe { vec.set_len(4); }Run
fn swap_remove(&mut self, index: usize) -> T
Removes an element from anywhere in the vector and return it, replacing it with the last element.
This does not preserve ordering, but is O(1).
Panics
Panics if index
is out of bounds.
Examples
let mut v = vec!["foo", "bar", "baz", "qux"]; assert_eq!(v.swap_remove(1), "bar"); assert_eq!(v, ["foo", "qux", "baz"]); assert_eq!(v.swap_remove(0), "foo"); assert_eq!(v, ["baz", "qux"]);Run
fn insert(&mut self, index: usize, element: T)
Inserts an element at position index
within the vector, shifting all
elements after it to the right.
Panics
Panics if index
is out of bounds.
Examples
let mut vec = vec![1, 2, 3]; vec.insert(1, 4); assert_eq!(vec, [1, 4, 2, 3]); vec.insert(4, 5); assert_eq!(vec, [1, 4, 2, 3, 5]);Run
fn remove(&mut self, index: usize) -> T
Removes and returns the element at position index
within the vector,
shifting all elements after it to the left.
Panics
Panics if index
is out of bounds.
Examples
let mut v = vec![1, 2, 3]; assert_eq!(v.remove(1), 2); assert_eq!(v, [1, 3]);Run
fn retain<F>(&mut self, f: F) where F: FnMut(&T) -> bool
Retains only the elements specified by the predicate.
In other words, remove all elements e
such that f(&e)
returns false
.
This method operates in place and preserves the order of the retained
elements.
Examples
let mut vec = vec![1, 2, 3, 4]; vec.retain(|&x| x%2 == 0); assert_eq!(vec, [2, 4]);Run
fn dedup_by_key<F, K>(&mut self, key: F) where F: FnMut(&mut T) -> K, K: PartialEq
Removes consecutive elements in the vector that resolve to the same key.
If the vector is sorted, this removes all duplicates.
Examples
#![feature(dedup_by)] let mut vec = vec![10, 20, 21, 30, 20]; vec.dedup_by_key(|i| *i / 10); assert_eq!(vec, [10, 20, 30, 20]);Run
fn dedup_by<F>(&mut self, same_bucket: F) where F: FnMut(&mut T, &mut T) -> bool
Removes consecutive elements in the vector that resolve to the same key.
If the vector is sorted, this removes all duplicates.
Examples
#![feature(dedup_by)] use std::ascii::AsciiExt; let mut vec = vec!["foo", "bar", "Bar", "baz", "bar"]; vec.dedup_by(|a, b| a.eq_ignore_ascii_case(b)); assert_eq!(vec, ["foo", "bar", "baz", "bar"]);Run
fn push(&mut self, value: T)
Appends an element to the back of a collection.
Panics
Panics if the number of elements in the vector overflows a usize
.
Examples
let mut vec = vec![1, 2]; vec.push(3); assert_eq!(vec, [1, 2, 3]);Run
fn pop(&mut self) -> Option<T>
Removes the last element from a vector and returns it, or None
if it
is empty.
Examples
let mut vec = vec![1, 2, 3]; assert_eq!(vec.pop(), Some(3)); assert_eq!(vec, [1, 2]);Run
fn append(&mut self, other: &mut Self)
1.4.0
Moves all the elements of other
into Self
, leaving other
empty.
Panics
Panics if the number of elements in the vector overflows a usize
.
Examples
let mut vec = vec![1, 2, 3]; let mut vec2 = vec![4, 5, 6]; vec.append(&mut vec2); assert_eq!(vec, [1, 2, 3, 4, 5, 6]); assert_eq!(vec2, []);Run
fn drain<R>(&mut self, range: R) -> Drain<T> where R: RangeArgument<usize>
1.6.0
Create a draining iterator that removes the specified range in the vector and yields the removed items.
Note 1: The element range is removed even if the iterator is not consumed until the end.
Note 2: It is unspecified how many elements are removed from the vector,
if the Drain
value is leaked.
Panics
Panics if the starting point is greater than the end point or if the end point is greater than the length of the vector.
Examples
let mut v = vec![1, 2, 3]; let u: Vec<_> = v.drain(1..).collect(); assert_eq!(v, &[1]); assert_eq!(u, &[2, 3]); // A full range clears the vector v.drain(..); assert_eq!(v, &[]);Run
fn clear(&mut self)
Clears the vector, removing all values.
Examples
let mut v = vec![1, 2, 3]; v.clear(); assert!(v.is_empty());Run
fn len(&self) -> usize
Returns the number of elements in the vector.
Examples
let a = vec![1, 2, 3]; assert_eq!(a.len(), 3);Run
fn is_empty(&self) -> bool
Returns true
if the vector contains no elements.
Examples
let mut v = Vec::new(); assert!(v.is_empty()); v.push(1); assert!(!v.is_empty());Run
fn split_off(&mut self, at: usize) -> Self
1.4.0
Splits the collection into two at the given index.
Returns a newly allocated Self
. self
contains elements [0, at)
,
and the returned Self
contains elements [at, len)
.
Note that the capacity of self
does not change.
Panics
Panics if at > len
.
Examples
let mut vec = vec![1,2,3]; let vec2 = vec.split_off(1); assert_eq!(vec, [1]); assert_eq!(vec2, [2, 3]);Run
impl<T: Clone> Vec<T>
[src]
fn resize(&mut self, new_len: usize, value: T)
1.5.0
Resizes the Vec
in-place so that len()
is equal to new_len
.
If new_len
is greater than len()
, the Vec
is extended by the
difference, with each additional slot filled with value
.
If new_len
is less than len()
, the Vec
is simply truncated.
Examples
let mut vec = vec!["hello"]; vec.resize(3, "world"); assert_eq!(vec, ["hello", "world", "world"]); let mut vec = vec![1, 2, 3, 4]; vec.resize(2, 0); assert_eq!(vec, [1, 2]);Run
fn extend_from_slice(&mut self, other: &[T])
1.6.0
Clones and appends all elements in a slice to the Vec
.
Iterates over the slice other
, clones each element, and then appends
it to this Vec
. The other
vector is traversed in-order.
Note that this function is same as extend
except that it is
specialized to work with slices instead. If and when Rust gets
specialization this function will likely be deprecated (but still
available).
Examples
let mut vec = vec![1]; vec.extend_from_slice(&[2, 3, 4]); assert_eq!(vec, [1, 2, 3, 4]);Run
