Descrizione

What's missing?

Rocket currently re-exports the async_trait crate for use with its Fairing (and possibly others). As of rust 1.75.0 this is no longer needed, therefore it would be nice to get rid of this dependency and use actual async functions for these traits.

This generally improves compile times, dependency count and IDE responsiveness.

Ideal Solution

For v0.6, remove async_trait (or put its usage behind a feature) and use async functions directly. This would raise the MSRV to 1.75.0.

Why can't this be implemented outside of Rocket?

This is an integral part of Rocket.

Are there workarounds usable today?

No. You bypass the need for the macro attribute by returning a Box<dyn Future<Output = T> + Send + 'a>, but this is unwieldy.

System Checks

  • I do not believe that this feature can or should be implemented outside of Rocket.
