Struct kalloc::cached::Cached[−][src]

pub struct Cached<T> { /* fields omitted */ }
Expand description

Allocator with cached pages.

Implementations

impl<P: Unsigned + PowerOfTwo + 'static> Cached<MultiBuddySystem<P>>[src]

pub unsafe fn alloc(&mut self, layout: Layout) -> *mut u8[src]

Allocate memory according to layout.

Due to the cache layer, this operation is amotized O(logN) and maybe O(N) in worst case. But it’s usually O(1) and much faster than O(logN).

pub unsafe fn dealloc(&mut self, ptr: *mut u8, layout: Layout)[src]

Free the memory pointed by ptr with specified layout.

This operation is O(1).
