Struct MemoryPool 

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

Memory pool for reducing allocation overhead.

A capacity-bounded, lock-free object pool: Self::deallocate stores up to max_size objects for reuse and Self::allocate pops a stored object or falls back to T::default(). The freelist mechanics live in LockFreeStack; this type only adds the pool vocabulary (allocate/deallocate) over the stack’s fixed slot capacity.

Implementations

impl<T> MemoryPool<T>

pub fn new(max_size: usize) -> Self

Create a new memory pool retaining at most max_size objects.

pub fn allocate(&self) -> T

where T: Default,

Allocate an object from the pool or create new if pool is empty

pub fn deallocate(&self, item: T)

Return an object to the pool for reuse.

When the pool already holds max_size objects the item is dropped; this is the pool’s documented retention cap, not an error condition.

pub fn size(&self) -> usize

Get current pool size
