> Rocket says it requires a nightly version of rust[0] - why is that necessary

I often joke that Rocket deliberately uses every single unstable feature solely to stymie the Rust developers' attempt to prioritize which features to stabilize. :P I'm kidding of course (hi, sbenitez!), but it's true that I've never seen any Rust project so taken with nightly features as Rocket is.

i128 really surprises me. Why would a web framework need 128 bit integers?

It appears u128s are used to intern strings. i.e. efficient uuids.
