Struct buddy_system_allocator::LockedFrameAllocator

pub struct LockedFrameAllocator<const ORDER: usize = 32>(/* private fields */);

A locked version of FrameAllocator

Usage

Create a locked frame allocator and add frames to it:

use buddy_system_allocator::*;
let mut frame = LockedFrameAllocator::<32>::new();
assert!(frame.lock().alloc(1).is_none());

frame.lock().add_frame(0, 3);
let num = frame.lock().alloc(1);
assert_eq!(num, Some(2));
let num = frame.lock().alloc(2);
assert_eq!(num, Some(0));
