#[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.
