    Super excited for Rocket on stable Rust. I hope that release comes out soon.

    1. 2

      WIll be interesting to compare rocket with actix-web, now that both can be used on stable. Was using actix-web until now, and except for path notations you already have a bunch of things like auto-deserializing of json etc.

    2. 1

      What exactly is “proc_macro_hygiene” ? I never understood what it does / why you need it.

      1. 5

        hygiene refers to creating new identifiers without colliding with anything from outside of the macro.

        It allows macros behave more like functions with their local variables, rather than like C macros which can grab anything they want.
