Struct alloc_many_collections::vec::Vec

pub struct Vec<A, T> where
    A: Alloc,  { /* fields omitted */ }

A contiguous growable array type, written Vec<T> but pronounced 'vector'.

Methods

impl<A, T> Vec<A, T> where
    A: Alloc, 

pub fn new() -> Self

Constructs a new, empty Vec<T>

pub fn capacity(&self) -> usize

Returns the number of elements the vector can hold without reallocating.

pub fn push(&mut self, elem: T)

Appends an element to the back of a collection.

pub fn pop(&mut self) -> Option<T>

Removes the last element from a vector and returns it, or None if it is empty.

pub fn reserve(&mut self, additional: usize)

Reserves capacity for at least additional more elements to be inserted in the given Vec.

Trait Implementations

impl<A, T> Deref for Vec<A, T> where
    A: Alloc, 

type Target = [T]

The resulting type after dereferencing.

fn deref(&self) -> &[T]

Dereferences the value.

impl<A, T> DerefMut for Vec<A, T> where
    A: Alloc, 

fn deref_mut(&mut self) -> &mut [T]

Mutably dereferences the value.
