Struct BlockPool 

pub struct BlockPool<const BLOCK_SIZE: usize, const NUM_BLOCKS: usize, const BITMAP_SIZE: usize> { /* private fields */ }

Block-based memory pool with fixed-size blocks

More efficient for frequent allocations/deallocations of similar sizes

Implementations

impl<const BLOCK_SIZE: usize, const NUM_BLOCKS: usize, const BITMAP_SIZE: usize> BlockPool<BLOCK_SIZE, NUM_BLOCKS, BITMAP_SIZE>

pub const fn new() -> Self

Create a new block pool

Panics

Panics if BITMAP_SIZE is not sufficient for NUM_BLOCKS

Trait Implementations

impl<const BLOCK_SIZE: usize, const NUM_BLOCKS: usize, const BITMAP_SIZE: usize> Default for BlockPool<BLOCK_SIZE, NUM_BLOCKS, BITMAP_SIZE>

fn default() -> Self

Returns the “default value” for a type.

impl<const BLOCK_SIZE: usize, const NUM_BLOCKS: usize, const BITMAP_SIZE: usize> MemoryPool for BlockPool<BLOCK_SIZE, NUM_BLOCKS, BITMAP_SIZE>

fn allocate(&self, size: usize, align: usize) -> Result<NonNull<u8>>

Allocate memory from the pool

unsafe fn deallocate( &self, ptr: NonNull<u8>, _size: usize, _align: usize, ) -> Result<()>

Deallocate memory back to the pool

fn capacity(&self) -> usize

Get the total capacity of the pool

fn used(&self) -> usize

Get the currently used bytes

unsafe fn reset(&self) -> Result<()>

Reset the pool (deallocate all)

fn available(&self) -> usize

Get the available bytes
