I am currently mostly working on integrating PRs into my arithmetic/boolean/string expression evaluation crate evalexpr.

But I am also in the process of creating a typed session handling crate for web frameworks like tower/axum. The existing crates all seem to only allow associating a hashtable with a session, which seems unnecessary if I can express the possible states of a session with e.g. an enum. It’s pretty much work in progress though. There is the core library typed-session as well as an implementation for axum typed-session-axum
