I know actix uses lots of generics and macros to match up your functions with varying signatures to Handlers for a request. That might be a reason why it’s slow but I don’t know enough about Rust compilation to be sure. Can’t you put the web stuff in another crate that depends on the main library crate? That way you can build and test your library without all the actix/web stuff.
