pub unsafe fn dealloc(ptr: *mut u8, layout: Layout)Expand description
Deallocate memory with the global allocator.
This function forwards calls to the GlobalAlloc::dealloc method
of the allocator registered with the #[global_allocator] attribute
if there is one, or the std crate’s default.
This function is expected to be deprecated in favor of the dealloc method
of the Global type when it and the Allocator trait become stable.
§Safety
See GlobalAlloc::dealloc.
