Struct TwoBufferBumpAllocator 

pub struct TwoBufferBumpAllocator { /* private fields */ }

Two-buffer bump allocator system for safe multi-pass compilation

This system solves several problems with the original single-buffer approach:

1. Enables intermediate memory cleanup between passes
2. Prevents stack overflow through controlled recursion depth
3. Provides safe lifetime management for buffer swapping
4. Maintains performance benefits of bump allocation

Implementations

impl TwoBufferBumpAllocator

pub fn new() -> Self

Creates a new two-buffer allocator system

pub fn current(&self) -> &Bump

Gets the current active buffer

pub fn next(&self) -> &Bump

Gets the next buffer (for output of current pass)

pub fn swap_and_clear(self) -> Self

Swaps buffers and clears the now-unused buffer Returns a new instance with swapped buffers for safe lifetime management

pub fn with_max_recursion_depth(self, depth: usize) -> Self

Sets maximum recursion depth for stack overflow protection

pub fn max_recursion_depth(&self) -> usize

Gets maximum recursion depth
