What are some mind blowing Rust tricks?
What are some mind blowing Rust tricks?
If we were to create a Rust version of this page for Haskell, what cool programming techniques would you add to it?
You're viewing a single thread.
Rust isn't really a language that lends itself to terse point-free functional idioms... The sort of examples I might want to share would probably require a bit more context, certainly more code. Like I think type guards and arena allocation are cool and useful tricks but I don't think I could write a neat little example showing or motivating either
Yeah I don't mean just terse functional idioms. Any programming technique that blew your mind the first time you came across it would qualify.
Type guards, then :) very cool, much compiler power, love it
Do you mean RAII guards
https://rust-unofficial.github.io/patterns/patterns/behavioural/RAII.html
Or match guards?
https://doc.rust-lang.org/rust-by-example/flow_control/match/guard.html
Maybe they're referring to "where clauses"?
Indeed I am. Forgot the name, lol, not worked with rust for a few months 😅
