CastSizedExact

zerocopy::pointer::cast

Enum CastSizedExact 

Source 
pub enum CastSizedExact {}
Expand description

A pointer cast which preserves the set of referent bytes of a statically-sized referent.

§Safety

The implementation of Project uses a compile-time assertion to guarantee that Dst has the same size as Src. Thus, CastSizedExact has a sound implementation of Project for all Src and Dst – the caller may pass any Src and Dst without being responsible for soundness.
