Official crates.io release

[danielhenrymantilla]

This makes the long-living master branch of safer-ffi finally releasable to crates.io again.

• To become a 0.1.0-rc1 release; a proper release may follow later.

• Despite the 0.1.0, future releases will probably be breaking anyways (0.2.0, etc.), since between the header generation (sensitive to name "mangling" schemes), the module naming, etc., it would be way too limiting for me to already try to aim for semver-compatible releases. I will, however, strive to make these breaking changes be soft / easy to tackle.

Notes

• The js support is still deemed too experimental to be made public (most users should just stick to using #[wasm_bindgen] or #[napi] directly), so it is not part of the crates.io package (in practice this is achieved by shadowing it with a ::cratesio-placeholder-package).

• C# "header" generation, on the other hand, is made public, even though it supports fewer features than C header generation (e.g., no pointers to a fn pointer), due to .NET being such a non-system programming language for certain things.

• repr_c::Box<[T]> now magically stands for the less ergonomic c_slice::Box<T>, hopefully improving the readability of function signatures.

  • This breaks repr_c::Box::new() due to type inference and function resolution, since repr_c::Box is currently implemented as a mere type alias. I may use a dedicated newtype/tuple struct if this is deemed too unergonomic. Box::new(…).into() is to be used instead.

• dyn Trait support! 🚀

• And a bunch of other things I may be forgetting.
