asynctraitproto

Async trait prototype using the desugarization described in RFC 3185 Static Async Fn in Traits.

It should be faster than async-trait because it doesn't use allocations on every invocation and type erasure.

Benchmark

Requires these feature flags and a nightly compiler: - #![feature(generic_associated_types)] - #![feature(type_alias_impl_trait)]

Example

```rust

![feature(genericassociatedtypes)]

![feature(typealiasimpl_trait)]

use asynctraitproto::asynctraitproto; struct Foo;

[asynctraitproto]

trait Bar { async fn wait(&self); }

[asynctraitproto]

impl Bar for Foo { async fn wait(&self) { sleep(Duration::from_secs(10)).await; } } ```
