Struct BumpAllocator

Source 
pub struct BumpAllocator { /* private fields */ }
Expand description

A simple bump allocator that allocates memory in a linear fashion. Memory is allocated by incrementing a pointer, and deallocated in bulk.

Implementations§

Source§

impl BumpAllocator

Source

pub const fn new() -> Self

Creates a new, uninitialized bump allocator.

Source

pub unsafe fn init(&mut self, heap_start: usize, heap_size: usize)

Initializes the bump allocator with a given heap start address and size.

§Safety

This function must only be called once and requires a valid memory region.
