Trait CartablePointerLike 

pub unsafe trait CartablePointerLike: StableDeref + Sealed { }

An object fully representable by a non-null pointer.

Safety

Implementer safety:

1. into_raw transfers ownership of the values referenced by StableDeref to the caller, if there is ownership to transfer
2. drop_raw returns ownership back to the impl, if there is ownership to transfer
3. into_raw must not return the sentinel pointer

Note: the pointer NonNull<Self::Raw> may or may not be aligned and it should never be dereferenced. Rust allows unaligned pointers; see std::ptr::read_unaligned.

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.
