Struct FixedPool 

pub struct FixedPool<const SIZE: usize, const ALIGN: usize> { /* private fields */ }

Fixed-size memory pool for embedded systems

Provides O(1) allocation and deallocation from a pre-allocated buffer. Suitable for real-time systems with deterministic memory requirements.

Implementations

impl<const SIZE: usize, const ALIGN: usize> FixedPool<SIZE, ALIGN>

pub const fn new(block_size: usize) -> Self

Create a new fixed pool with given block size

Arguments

• block_size - Size of each allocatable block (will be aligned to ALIGN)

Examples

use kizzasi_core::embedded_alloc::FixedPool;

// Pool with 1KB, 8-byte aligned blocks
let pool: FixedPool<1024, 8> = FixedPool::new(64);

pub fn alloc(&self) -> Option<NonNull<u8>>

Allocate a block from the pool

Returns None if the pool is exhausted.

pub unsafe fn dealloc(&self, _ptr: NonNull<u8>)

Deallocate a block back to the pool

Safety

The pointer must have been allocated from this pool and not already freed.

pub unsafe fn reset(&self)

Reset the pool, freeing all allocations

Safety

Only call this when you’re certain no outstanding allocations exist.

pub fn available(&self) -> usize

Get the number of available blocks

pub const fn capacity(&self) -> usize

Get total number of blocks in the pool

pub const fn block_size(&self) -> usize

Get block size
