Super excited for Rocket on stable Rust. I hope that release comes out soon.
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.
What exactly is “proc_macro_hygiene” ? I never understood what it does / why you need it.
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.
