Detailed Description

Internal definition of a memory arena.

An arena is a fast, region-based allocator. It pre-allocates a single block of memory and serves subsequent small allocation requests by simply "bumping" a pointer. All memory allocated from an arena is freed at once by destroying the arena itself, eliminating the need to track individual allocations.

Member Data Documentation

block_size

size_t infix_arena_t::block_size

The size of this specific block's buffer, for chained arenas.

buffer

char* infix_arena_t::buffer

The backing memory buffer for the arena.

capacity

size_t infix_arena_t::capacity

The total size of the buffer.

current_offset

size_t infix_arena_t::current_offset

The current high-water mark of allocation.

error

bool infix_arena_t::error

A flag set if any allocation fails, preventing subsequent allocations.

next_block

struct infix_arena_t* infix_arena_t::next_block

A pointer to the next block in the chain, if this one is full.
