What makes Rust still rather inaccessible for me is the difficulty in finding «functions I can apply to an argument of type X» and «functions that return a valu

  That would be what Hoogle is for Haskell: https://www.haskell.org/hoogle/ https://www.haskell.org/hoogle/ Could you start by grepping API docs?

    > grepping API docs Of course, but that's still painfully slow and awkward. It's exactly the kind of repetitive crap we programmers are born to automate.

  When you search in the API documentation, you will find 3 tabs at the top: "In Names", "In Parameters" and "In Return Types". Example: https://doc.rust-lang.org/std/?search=option https://doc.rust-lang.org/std/?search=option

  The official docs have limited support for it, if you search for i32[0] the default facet is "in names" but you can use the "in parameters" and "in return types" tabs for these. I don't know how well these handle abstract types and it's nowhere near hoogle convenience, but there you are (there were efforts to port/replicate hoogle a few years back but the few I remember seem to have been abandoned, specifying a search syntax is probably non-trivial as well given Rust's signatures are not as convenient as Haskell's there)/ [0] https://doc.rust-lang.org/std/?search=i32 https://doc.rust-lang.org/std/?search=i32
