Struct MemStack 

pub struct MemStack { /* private fields */ }

A memory stack for temporary allocations.

This provides fast, stack-based allocation for scratch space needed by algorithms. Allocations are invalidated when the stack is reset.

Implementations

impl MemStack

pub fn new(req: StackReq) -> Self

Creates a new memory stack with the given requirement.

pub fn with_size(size: usize) -> Self

Creates a new memory stack with the given size.

pub fn remaining(&self) -> usize

Returns the remaining capacity.

pub fn reset(&mut self)

Resets the stack, invalidating all allocations.

pub fn alloc<T>(&mut self, count: usize) -> &mut [MaybeUninit<T>]

Allocates a slice of the given type.

Panics

Panics if there’s not enough space.

pub fn alloc_zeroed<T: Zeroable>(&mut self, count: usize) -> &mut [T]

Allocates and zeros a slice of the given type.

pub fn make_sub_stack(&mut self) -> MemStack

Creates a sub-stack with the remaining memory.

This is useful for recursive algorithms that need to pass scratch space to sub-operations.

Note: This is a placeholder implementation. A full implementation would use raw pointers to share the buffer without ownership transfer.
