Struct StackPool 

pub struct StackPool { /* private fields */ }

Pool-based allocator for thread stacks.

This allocator maintains separate free lists for each stack size class to minimize fragmentation and allocation overhead.

Implementations

impl StackPool

pub const fn new() -> Self

Create a new stack pool.

pub fn allocate(&self, size_class: StackSizeClass) -> Option<Stack>

Allocate a stack of the given size class.

This will first try to reuse a stack from the free list, and only allocate new memory if no suitable stack is available.

Arguments

• size_class - The desired stack size class

Returns

A new stack, or None if allocation fails.

pub fn deallocate(&self, stack: Stack)

Return a stack to the pool for reuse.

Arguments

• stack - The stack to return to the pool

pub fn stats(&self) -> (usize, usize, usize)

Get statistics about the stack pool.
