pub struct LazyHeap(/* private fields */);

A wrapper around slab_allocator_rs::LockedHeap that initializes the heap lazily.

Implementations

impl LazyHeap

pub const fn new(init: fn() -> LockedHeap) -> Self

Create a new LazyHeap with the given initialization function.

pub const fn empty() -> Self

Create a new LazyHeap with the default initialization function.

pub fn init(&self, begin: usize, len: usize)

Initialize the heap with the given range.

Trait Implementations

impl GlobalAlloc for LazyHeap

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

Allocates memory as described by the given layout.

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

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.
