linked_list_allocator 0.6.3

Simple allocator usable for no_std systems. It builds a linked list from the freed blocks and thus needs no additional data structures.


Build Status



Create a static allocator in your root module:

use linked_list_allocator::LockedHeap;

static ALLOCATOR: LockedHeap = LockedHeap::empty();

Before using this allocator, you need to init it:

pub fn init_heap() {
    let heap_start = …;
    let heap_end = …;
    let heap_size = heap_end - heap_start;
    unsafe {
        ALLOCATOR.lock().init(heap_start, heap_size);
