Struct alloc_compose::ChunkAlloc

pub struct ChunkAlloc<A, const SIZE: usize>(pub A);

Marks newly allocated and deallocated memory with a byte pattern.

When allocating unintitialized memory, the block is set to 0xCD. Before deallocating, the memory is set 0xDD. Those values are choosed according to Magic Debug Values to match the Visual Studio Debug Heap implementation.

Once, const_generics allows default implementations, the values may be alterd with a parameter.

🔬 This is a nightly-only experimental API. (allocator_api)

Deallocates the memory referenced by ptr.

unsafe fn grow(
    &mut self,
