Struct mnemos_alloc::heap::SingleThreadedLinkedListAllocator

pub struct SingleThreadedLinkedListAllocator {
    mlla: Mutex<Heap>,
}

A wrapper of linked_list_allocator::Heap that uses maitake::sync::Mutex.

This should ONLY be used in a single threaded context, which also includes NOT using it in interrupts.

If an allocation is attempted while the mutex is locked (e.g. we are pre-empted by a thread/interrupt), this allocator will panic.

This allocator MUST be initialized with a call to SingleThreadedLinkedListAllocator::init() before any allocations will succeed

Fields

mlla: Mutex<Heap>

Trait Implementations

impl UnderlyingAllocator for SingleThreadedLinkedListAllocator

const INIT: Self = _

A constant initializer of the allocator.

unsafe fn init(&self, start: NonNull<u8>, len: usize)

Initialize the allocator, if it is necessary to populate with a region of memory.

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

Allocate a region of memory

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

Deallocate a region of memory
