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);
}
}
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; requires nightly Rust.
AllocRef
trait is still regularly changed on the Rust side, so expect some regular breakage when using this feature.This crate is dual-licensed under MIT or the Apache License (Version 2.0). See LICENSE-APACHE and LICENSE-MIT for details.
