I would like to nominate my Transformer implementation using the Burn framework. The Topological Transformer innovates in KV-cache computation and other feats: crates.io: Rust Package Registry
It is a fork of my other crate nanogpt that is a porting og nanoGPT in Rust and it is based on this research paper: GitHub - tuned-org-uk/tauformer-paper: Topological Transformer paper

Thanks and cheers

I would like to self-nominate axum-autoroute.
It's a crate that we built and use in my company and that we recently decided to publish (see the recent announcement post: New crate: axum-autoroute ).

The goal of this crate is to ease the writing of OpenAPI documentation in the code for HTTP route handlers, for example by:

  • Avoiding to type the HTTP method or the handler path multiple times
  • Enforce that the HTTP responses returned by the HTTP handler are always documented

It is based on axum and utoipa.

downcast-rs. It generates implementation code for a Trait: Any to allow downcasting from dyn Trait (where the standard library only supports downcasting from dyn Any, apart from trait upcasting (dyn Trait → dyn Any) in edition 2024, which has limitations).

The typle crate provides the ability to constrain generic arguments to be tuples and supports manipulation of the tuple components.

Personally I found it has quite a few useful features for tuples related code
