Struct allocators::HeapAllocator

pub struct HeapAllocator;

Allocator stub that just forwards to heap allocation. It is recommended to use the HEAP constant instead of creating a new instance of this, to benefit from the static lifetime that it provides.

Trait Implementations

impl Debug for HeapAllocator

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Allocator for HeapAllocator

unsafe fn allocate_raw(&self, size: usize, align: usize) -> Result<Block, AllocatorError>

Attempt to allocate a block of memory.

unsafe fn deallocate_raw(&self, blk: Block)

Deallocate the memory referred to by this pointer.

fn allocate<T>(&self, val: T) -> Result<Allocated<T, Self>, (AllocatorError, T)> where Self: Sized

Attempts to allocate the value supplied to it.

fn make_place<T>(&self) -> Result<Place<T, Self>, AllocatorError> where Self: Sized

Attempts to create a place to allocate into. For the general purpose, calling allocate on the allocator is enough. However, when you know the value you are allocating is too large to be constructed on the stack, you should use in-place allocation.
