Struct ordnung::compact::Vec

pub struct Vec<T> { /* fields omitted */ }

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

Methods

impl<T> Vec<T>

pub fn new() -> Self

Constructs a new, empty Vec.

The vector will not allocate until elements are pushed onto it.

pub fn with_capacity(capacity: usize) -> Self

Constructs a new, empty Vec 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.

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

Appends an element to the back of a collection.

Panics

Panics if the number of elements in the vector overflows a u32.

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 clear(&mut self)

Clears the vector, removing all values.

Note that this method has no effect on the allocated capacity of the vector.

pub fn len(&self) -> usize

Returns the number of elements in the vector.

pub fn capacity(&self) -> usize

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

pub 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.

pub const fn as_ptr(&self) -> *const T

Returns a raw pointer to the vector's buffer.

pub fn as_mut_ptr(&mut self) -> *mut T

Returns an unsafe mutable pointer to the vector's buffer.

Trait Implementations

Creates a value from an iterator.

impl<T> IntoIterator for Vec<T>

type Item = T

The type of the elements being iterated over.
