Enum CastUnsized 

pub enum CastUnsized {}

A pointer cast which preserves or shrinks the set of referent bytes of a dynamically-sized referent.

Safety

The implementation of Project uses a compile-time assertion to guarantee that the cast preserves the set of referent bytes. Thus, CastUnsized has a sound implementation of Project for all Src and Dst – the caller may pass any Src and Dst without being responsible for soundness.

Trait Implementations

impl<Src, Dst> Project<Src, Dst> for CastUnsized

where Src: ?Sized + KnownLayout, Dst: ?Sized + KnownLayout<PointerMetadata = Src::PointerMetadata>,

fn project(src: PtrInner<'_, Src>) -> *mut Dst

Projects a pointer from Src to Dst.
