LockedHeap

✓ use linked_list_allocator::LockedHeap;

Initialize a global allocator with a fixed heap region.

use linked_list_allocator::LockedHeap; #[global_allocator] static ALLOCATOR: LockedHeap = LockedHeap::empty(); fn main() { let heap_start = 0x1000 as *mut u8; let heap_size = 4096; unsafe { ALLOCATOR.lock().init(heap_start, heap_size); } let _box = Box::new(42); }

Debug

Known issues

gotchaThe allocator is not thread-safe by default; use LockedHeap for global usage.

fix

Use `LockedHeap` (which wraps a spinlock) instead of `Heap` directly.

affects: >=0.10.0
