Struct StackAllocator 

pub struct StackAllocator<const N: usize> { /* private fields */ }

Stack-based allocator for fixed-size allocations

Maintains a stack of allocations and only allows deallocation in LIFO order

Implementations

impl<const N: usize> StackAllocator<N>

pub const fn new() -> Self

Create a new stack allocator

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

Allocate from the stack

Errors

Returns error if insufficient space or invalid alignment

pub unsafe fn pop(&self, size: usize) -> Result<()>

Pop the last allocation

Safety

Must be called in LIFO order matching allocations

pub fn used(&self) -> usize

Get current offset

pub fn available(&self) -> usize

Get remaining capacity

pub fn reset(&self)

Reset the allocator

Trait Implementations

impl<const N: usize> Default for StackAllocator<N>

fn default() -> Self

Returns the “default value” for a type.
