Struct PinnedVec 

pub struct PinnedVec<T> { /* private fields */ }

Vec-like structure whose elements never move.

Implementations

impl<T> PinnedVec<T>

pub fn new() -> Self

Create a new, empty PinnedVec. This method does not allocate.

pub fn len(&self) -> usize

Get the length of the PinnedVec (the number of elements inside).

pub fn capacity(&self) -> usize

Get the current capacity of the PinnedVec Pushing within capacity means no extra allocation. Pushing over capacity will cause allocation, increasing capacity.

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

Get a pinned reference to the element at the specified index, if it exists.

pub fn get_mut(&mut self, index: usize) -> Option<Pin<&mut T>>

Get a pinned mutable reference to the element at the specified index, if it exists.

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

Push an element to the end of the PinnedVec. Might cause the PinnedVec to allocate a new sub-vector.

pub fn pop(&mut self)

Remove the last element in the PinnedVec. The element is not returned because that would violate Pin invariant.

Panics

Panics if the vec is empty.

pub fn replace(&mut self, index: usize, item: T)

Replace the element at the specified index with another one. The element is not returned because that would violate Pin invariant.

Panics

Panics if index is not in the vec (i.e. len >= index).
