# `#[real_async_trait]` [![Build Status](https://travis-ci.org/4lDO2/real-async-trait-rs.svg?branch=master)](https://travis-ci.org/4lDO2/real-async-trait-rs) [![Crates.io](https://img.shields.io/crates/v/real-async-trait.svg)](https://crates.io/crates/real-async-trait) [![Documentation](https://docs.rs/real-async-trait/badge.svg)](https://docs.rs/real-async-trait/) This crate provides a proof-of-concept proc macro attribute that allows async traits to be possible, without wrapping everything in a `Box` and erase the types. This is made possible due to experimental `generic_associated_types` feature, as well as the unstable `type_alias_impl_trait` feature. ## Disclaimer The `generic_associated_types` feature is not unstable, but an "incomplete" experimental feature; rustc even gives you a warning when using it. __Don't use this in production code__. At the moment it's probably a better idea to use a type-erased async trait attribute proc macro, such as Dtolnay's `async-trait` crate, or a similar one. That said, it'd be awesome both for me and for the rust compiler if you could test this, find something that's missing in the compiler or here, and file an issue. ## License Licensed under either of * Apache License, Version 2.0 ([LICENSE-APACHE](LICENSE-APACHE) or http://www.apache.org/licenses/LICENSE-2.0) * MIT license ([LICENSE-MIT](LICENSE-MIT) or http://opensource.org/licenses/MIT) at your option. ## Contribution Unless you explicitly state otherwise, any contribution intentionally submitted for inclusion in the work by you, as defined in the Apache-2.0 license, shall be dual licensed as above, without any additional terms or conditions.
