pub struct LockedHeap<const ORDER: usize>(/* private fields */);

A locked version of Heap

Usage

Create a locked heap and add a memory region to it:

use base::alloc::heap::*;
let mut heap = LockedHeap::<32>::new();
unsafe {
    heap.lock().init(begin, size);
    // or
    heap.lock().add_to_heap(begin, end);
}

unsafe fn alloc(&self, layout: StdLayout) -> *mut u8

Allocates memory as described by the given layout.

unsafe fn dealloc(&self, ptr: *mut u8, layout: StdLayout)

Deallocates the block of memory at the given ptr pointer with the given layout.

unsafe fn alloc_zeroed(&self, layout: Layout) -> *mut u8

Behaves like alloc, but also ensures that the contents are set to zero before being returned.

unsafe fn realloc( &self, ptr: *mut u8, layout: Layout, new_size: usize, ) -> *mut u8

Shrinks or grows a block of memory to the given new_size in bytes. The block is described by the given ptr pointer and layout.
