I wonder if you might be attributing to me questions not asked by me.
I count 3 in the past week and 7 in the past month -- is this considered rude / impolite ?
I don't want to make excuses -- what's currently happening is that IntelliJ/Rust seems to be much faster at type inference of closures, so I'm rewriting lots of for loops in a more functional manner.
The issue I'm running into with the Iterator docs is that (1) I often guess the wrong English word, (2) then I'm linearly scanning through the 60+ function type signatures to see any match.
What would be really useful would be a better way to search fully expanded type signatures (aliases + where clauses get in the way here), i.e. being able to type (not literal regex)
"Fn(.*Option.*) -> Option.*"
and have it narrow down to functions that return an Option, and takes as input a Fn that takes Option as an input.
