10:33 < mlerner> hey all. I am interested in contributing to rust bitcoin, but unclear where to start / what would be the most helpful. I'm happy to help with test coverage if that would be useful
10:43 < sgeisler> Hi, welcome to rust-bitcoin :) if you want to get to know the library a bit better @stevenroose's hal tool might be a good starting point. https://github.com/stevenroose/hal/
10:44 < sgeisler> It exposes rust-bitcoin functionality as a CLI app and is quite easy to understand.
10:45 < sgeisler> Since it's still missing some functionality that might be a good start: identify missing functions, look how to implement them using rust-bitcoin, propose fixes for usability issues/missing functionality.

10:51 < sgeisler> Another interesting project would be implementing output selection and supporting functionality around the already existing PSBT data structures. @dongcarl can probably tell you more about that.
10:57 < dongcarl> Yeah coin selection would be excellent
10:57 < dongcarl> mlerner: Here's some good background http://diyhpl.us/wiki/transcripts/scalingbitcoin/tokyo-2018/edgedevplusplus/coin-selection/
10:58 < sgeisler> murch also wrote his master thesis about it: http://murch.one/wp-content/uploads/2016/11/erhardt2016coinselection.pdf
11:19 < sgeisler> andytoshi, stevenroose: could this function directly return an `ExtendedPrivKey` instead of a `Result<_, _>` https://github.com/rust-bitcoin/rust-bitcoin/blob/master/src/util/bip32.rs#L428 ?
11:20 < sgeisler> The possible errors seem to be of the "after addition of 32 byte value we don't have a valid key anymore" kind
11:21 < sgeisler> which as we decided in https://github.com/rust-bitcoin/rust-bitcoin/pull/247 is improbable enough to ignore

11:52 < andytoshi> sgeisler: yep looks like it
11:52 < andytoshi> i think i used a result to avoid having to write unwrap()
11:52 < andytoshi> but i probably should've

14:59 < stevenroose> andytoshi: yeah Results are so ergonomical both as a producer of a method and as a consumer that it's often convenient to just always use them :D
15:00 < stevenroose> I don't know about `add_assign` myself, the `from_slice` call should be safe, yes.
15:01 < stevenroose> I was thinking today that it'd be quite nice to have `impl <E: Encodable> ToHex for E` that serializes and hexes :D though I think rust-bitcoin still exposes the serialize_hex global function in the encode module
