Struct ArrayVec 

pub(crate) struct ArrayVec<T, const N: usize> {
    elements: [Option<T>; N],
    length: usize,
}

Array-backed append-only vector type.

Fields

elements: [Option<T>; N]

Elements of the set.

length: usize

Last populated element.

Implementations

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

pub fn new() -> Self

Create a new ArrayVec.

pub fn push(&mut self, item: T) -> Result<()>

Push an item into this ArrayVec.

pub fn get(&self, index: usize) -> Option<&T>

Get an element from this ArrayVec.

pub fn iter(&self) -> Iter<'_, T>

Iterate over the elements in this ArrayVec.

pub fn is_empty(&self) -> bool

Is this ArrayVec empty?

pub fn len(&self) -> usize

Get the number of elements in this ArrayVec.

pub fn last(&self) -> Option<&T>

Get the last item from this ArrayVec.

pub fn into_array(self) -> [Option<T>; N]

Extract the inner array.

Trait Implementations

impl<T, const N: usize> AsMut<[Option<T>]> for ArrayVec<T, N>

fn as_mut(&mut self) -> &mut [Option<T>]

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

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

fn as_ref(&self) -> &[Option<T>]

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) -> ArrayVec<T, N>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

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

fn default() -> Self

Returns the “default value” for a type.

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

fn cmp(&self, other: &ArrayVec<T, N>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

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

fn eq(&self, other: &ArrayVec<T, N>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

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

fn partial_cmp(&self, other: &ArrayVec<T, N>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
