Trait CastExact 

pub unsafe trait CastExact<Src: ?Sized, Dst: ?Sized>: Cast<Src, Dst> { }

A Cast which does not shrink the set of referent bytes.

Safety

A CastExact projection must preserve the set of referent bytes.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
