Struct slab_allocator_rs::LockedHeap

pub struct LockedHeap(_);

Implementations

impl LockedHeap

pub const fn empty() -> LockedHeap

pub unsafe fn init(&self, heap_start_addr: usize, size: usize)

Safety

This function is unsafe because it can cause undefined behavior if the given address is invalid.

pub unsafe fn new(heap_start_addr: usize, heap_size: usize) -> LockedHeap

Creates a new heap with the given heap_start_addr and heap_size. The start address must be valid and the memory in the [heap_start_addr, heap_bottom + heap_size) range must not be used for anything else.

Safety

This function is unsafe because it can cause undefined behavior if the given address is invalid.

Trait Implementations

impl Deref for LockedHeap

type Target = Mutex<Option<Heap>>

The resulting type after dereferencing.

fn deref(&self) -> &Mutex<Option<Heap>>

Dereferences the value.

impl GlobalAlloc for LockedHeap

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

Allocate memory as described by the given layout.

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

Deallocate 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

Shrink or grow a block of memory to the given new_size. The block is described by the given ptr pointer and layout.
