Struct BuddyAllocator 

pub struct BuddyAllocator { /* private fields */ }

Bitmap-tree-based buddy allocator, loosely based on https://github.com/Restioson/buddy-allocator-workshop.

Implementations

impl BuddyAllocator

pub fn new(max_order: u8, o0_size: u64) -> Self

Creates a new buddy allocator.

• max_order specifies the max allocatable order.
• o0_size specifies the physical size of a block of order 0.

pub fn order_of(size: NonZeroU64, o0_size: u64) -> u8
