async_t

This library allows for zero-cost compile-time async-traits. This library needs nightly and features generic_associated_types and type_alias_impl_trait to be enabled. It doesn't support dynamic dispatch and has limited generic support. Compiling in stable will automatically use dtolnay's async_trait instead.

```rust

[async_trait]

trait Spawn { // supports self, &self, &mut self and no self async fn spawn() -> JoinHandle<()>; }

[async_trait]

impl Spawn for Spawner { async fn spawn() -> JoinHandle<()> { task::spawn(async { // ... }) } }

async fn spawn() -> JoinHandle<()> { T::spawn().await } ```
