A single-header-only opaque type-erased object handle library for C++. For interop with C libraries that use incomplete types and for general type-erasure and type-safe internal casting.

Avril 8168dd904d Added opaque_handle::ptr_cast(): Use `try_cast()` for complete types, and `unsafe_cast()` for incomplete types. This is used *only* for `operator [const] T*()`, since this is intended for C interop. `operator->` and `operator*` will only work with complete types, as they should. ...

include	Added opaque_handle::ptr_cast(): Use `try_cast()` for complete types, and `unsafe_cast()` for incomplete types. This is used *only* for `operator [const] T*()`, since this is intended for C interop. `operator->` and `operator*` will only work with complete types, as they should.	3 years ago
src	With fully incomplete types, `unsafe_cast` is used instead of `try_cast` in `operator [const] T*()`.	3 years ago
.gitignore	Tested all variants of `make_opaque_handle()`, they all work. `opaque_handle` workable in a project; however. `try_cast()` does not work correctly and will not return `nullptr` if the types are wrong. TODO: Fixing this will require a refactor to use another inheritance graph of objects instead of `void*`, however, this is intended for work using C interfaces, so it"s not a high priority for it to work on polymorphic types.	3 years ago
