This crate provides the FreeList type to allocate pages/frames of virtual/physical memory:
use free_list::{FreeList, PageLayout};
let mut free_list = FreeList::<16>::new();
unsafe {
free_list.deallocate((0x1000..0x5000).try_into().unwrap()).unwrap();
}
assert_eq!(free_list.free_space(), 0x4000);
let layout = PageLayout::from_size(0x4000).unwrap();
assert_eq!(free_list.allocate(layout).unwrap(), (0x1000..0x5000).try_into().unwrap());For API documentation, see the docs.
