linked-list-allocator

Documentation

Usage

Create a static allocator in your root module:

use linked_list_allocator::LockedHeap;

#[global_allocator]
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);
    }
}

Features

• use_spin (default): Provide a LockedHeap type that implements the GlobalAlloc trait by using a spinlock.
• alloc_ref: Provide an implementation of the unstable AllocRef trait.
  • Warning: The AllocRef trait is still regularly changed on the Rust side, so expect some regular breakage when using this feature.
