Struct HeapArena 

pub struct HeapArena { /* private fields */ }

A memory arena for temporary allocations

This provides push/pop semantics similar to zsh’s heap management, but uses Rust’s standard memory management under the hood.

Implementations

impl HeapArena

pub fn new() -> Self

pub fn push(&mut self)

Push a new heap state (like zsh’s pushheap)

pub fn pop(&mut self)

Pop and free all allocations since the last push (like zsh’s popheap)

pub fn free_current(&mut self)

Free allocations in current generation but keep generation marker (like zsh’s freeheap)

pub fn alloc_string(&mut self, s: String) -> &str

Allocate a string in the current generation

pub fn alloc_bytes(&mut self, bytes: Vec<u8>) -> &[u8]

Allocate bytes in the current generation

pub fn depth(&self) -> usize

Get current stack depth

Trait Implementations

impl Default for HeapArena

fn default() -> Self

Returns the “default value” for a type.
