Struct ArrayVec

pub struct ArrayVec<T, const N: usize> { /* private fields */ }

Small on-stack vector of max length N.

Implementations

impl<T, const N: usize> ArrayVec<T, N>

pub const fn new() -> Self

Returns an empty vector.

pub const fn len(&self) -> usize

Returns the number of elements in the vector, also referred to as its ‘length’.

pub const fn is_empty(&self) -> bool

Returns true if the vector contains no elements.

pub unsafe fn push(&mut self, item: T)

Appends an element to the back of a collection.

Safety

The following must be true:

• The length of this vector is less than N.

pub const fn get(&self, n: u8) -> Option<&T>

Returns a reference to an element.

pub unsafe fn into_inner(self) -> [MaybeUninit<T>; N]

Returns the inner data without dropping its elements.

Safety

The caller is responsible for calling the destructor for len initialized items in the returned array.

Trait Implementations

impl<R, const N: usize> AsRef<[R]> for ArrayVec<R, N>

fn as_ref(&self) -> &[R]

Converts this type into a shared reference of the (usually inferred) input type.

impl<T: Clone, const N: usize> Clone for ArrayVec<T, N>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T, const N: usize> Default for ArrayVec<T, N>

fn default() -> Self

Returns the “default value” for a type.

impl<T, const N: usize> Drop for ArrayVec<T, N>

fn drop(&mut self)

Executes the destructor for this type.

impl<T, const N: usize> IntoIterator for ArrayVec<T, N>

type Item = T

The type of the elements being iterated over.

type IntoIter = ArrayVecIntoIter<T, N>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
