Struct BucketArrayMemory

Source 
pub struct BucketArrayMemory<const N: usize, const M: usize, T: Copy>([[MaybeUninit<T>; M]; N]);
Expand description

Backing memory for a single key or value bucket array

Describes N buckets which each hold at most M items of type T.

Implements Uninit. Structs and unions made from BucketArrayMemory can be soundly marked as Uninit.

Trait Implementations§

Source§

impl<const N: usize, const M: usize, T: Clone + Copy> Clone for BucketArrayMemory<N, M, T>

Source§

fn clone(&self) -> BucketArrayMemory<N, M, T>

Returns a copy of the value. Read more

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

Performs copy-assignment from source. Read more
Source§

impl<const N: usize, const M: usize, T: Copy> Uninit for BucketArrayMemory<N, M, T>

Implements the Uninit trait. This memory is always assumed to be uninitialized unless we hold a mutable reference paired with bucket usage information.

SAFETY: We can implement Uninit for BucketArrayMemory because it’s Copy and it contains only MaybeUninit bits.

Source§

fn alloc() -> Box<Self>

Allocate new uninitialized memory, returning a new Box.
