Trait Project 

pub unsafe trait Project<Src: ?Sized, Dst: ?Sized> {
    // Required method
    fn project(src: PtrInner<'_, Src>) -> *mut Dst;
}

A pointer cast or projection.

Safety

The implementation of project must satisfy its safety post-condition.

Required Methods

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

Projects a pointer from Src to Dst.

Users should generally not call project directly, and instead should use high-level APIs like [PtrInner::project] or Ptr::project.

Safety

The returned pointer refers to a non-strict subset of the bytes of src’s referent, and has the same provenance as src.

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.
