Trait Implementations

impl BucketCapacity for BucketWithHeader

fn capacity(&self) -> u64

fn capacity_pow2(&self) -> u8

impl BucketOccupied for BucketWithHeader

fn occupy(&mut self, element: &mut [u8], ix: usize)

set entry at ix as occupied (as opposed to free)

fn free(&mut self, element: &mut [u8], ix: usize)

set entry at ix as free

fn is_free(&self, element: &[u8], _ix: usize) -> bool

return true if entry at ix is free

fn offset_to_first_data() -> usize

of bytes prior to first data held in the element.

fn new(capacity: Capacity) -> Self

initialize this struct capacity is the number of elements allocated in the bucket

fn copying_entry( &mut self, _element_new: &mut [u8], _ix_new: usize, _other: &Self, _element_old: &[u8], _ix_old: usize )

copying entry. Any in-memory (per-bucket) data structures may need to be copied for this ix_old. no-op by default

impl Clone for BucketWithHeader

fn clone(&self) -> BucketWithHeader

Returns a copy of the value.

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

Performs copy-assignment from source.
