Structs

Layout	Layout of a block of memory.
LayoutErr	The parameters given to Layout::from_size_align or some other Layout constructor do not satisfy its documented constraints.
AllocErr	Experimental The AllocErr error indicates an allocation failure that may be due to resource exhaustion or to something wrong when combining the given input arguments with this allocator.
