| 08:44:51 | FromDiscord | <kapendev> I can also imagine they do that for their bindings/wrappers. |

| 08:54:25 | FromDiscord | <lainlaylie> In reply to @blashyrk "Does anyone know if": are you looking for something like mapIt? |
| 08:55:42 | FromDiscord | <blashyrk> In reply to @lainlaylie "are you looking for": Yes but mapIt works for seqs (it's from sequtils) only I think, and also allocates to the best of my knowledge. |
| 08:57:59 | FromDiscord | <blashyrk> Oooh but I just realized there's an `inject` pragma, that should do the trick (with a template) |
| 09:01:05 | FromDiscord | <lainlaylie> mapIt works on arrays (or anything it can iterate over) but indeed returns a seq. there's no closure involve though, the ast passed as argument is expanded directly |
| 09:01:16 | FromDiscord | <lainlaylie> (edit) "involve" => "involved" |

| 09:24:35 | FromDiscord | <lainlaylie> you can, that's what mapIt does |
| 09:25:37 | FromDiscord | <lainlaylie> this kind of error usually means something in the template is failing to compile |
| 09:26:31 | FromDiscord | <lainlaylie> In reply to @blashyrk "Thanks! I'd like to": though i can't debug your exact code because it's missing some definitions and the actual call to `magnitude` |
| 09:27:08 | FromDiscord | <griffith1deadly> In reply to @lainlaylie "you can, that's what": didn't know that |
| 09:32:40 | FromDiscord | <hawkey5212> In reply to @fabric.input_output "example?": I'd love to see an example as well. Curious about what constitutes abuse of `Result` or `Option` in rust.↵↵In my experience, nothing gets past code review without at least being noticed if it looks like inappropriate use. |
| 09:34:48 | FromDiscord | <blashyrk> In reply to @lainlaylie "though i can't debug": I think it's because it might be impossible to infer the U param this way... So I also tried this to no avail:↵↵https://play.nim-lang.org/#pasty=JWwuhmWd |
| 09:35:42 | FromDiscord | <blashyrk> I saw that `mapIt` uses some moderately complex machinery to figure out the output type, maybe I need to copy that |
| 09:37:28 | FromDiscord | <lainlaylie> `type resType = typeof((let it {.inject.} = default(T); body))` |
| 09:37:49 | FromDiscord | <lainlaylie> the problem is in typeof(body), there is no `it` so it fails to compile |
| 09:43:29 | FromDiscord | <blashyrk> Thanks, that did the trick! 🙂 |
| 09:44:25 | FromDiscord | <blashyrk> Seems kinda "ugly" to use `it` also in the intermediate step for the type, but I'm not complaining 😄 |
| 09:44:41 | FromDiscord | <0xfab_10> In reply to @kapendev "In Rust land this": why would it not be? |
| 09:45:15 | FromDiscord | <blashyrk> Ah but it only works if T is the same as U 😦 ... Back to the drawing board |
| 09:48:10 | FromDiscord | <lainlaylie> In reply to @blashyrk "Ah but it only": that shouldn't be the case |

| 10:07:33 | FromDiscord | <nnsee> In reply to @fabric.input_output "why would it not": don't you know? rust prevents all errors from ever happening |
| 10:08:53 | FromDiscord | <nnsee> on a more serious note, the type system is quite powerful and the compiler should stop some invalid states from even being possible, but... that only gets you so far. errors occurring at runtime are runtime errors and no amount of compiler magic changes that |
| 10:27:05 | FromDiscord | <0xfab_10> also sometimes it's not the function's responsibility to handle the error so the best you can do is just pass it along |
| 10:28:19 | FromDiscord | <hawkey5212> sent a code paste, see https://play.nim-lang.org/#pasty=gGuVPFPT |
| 10:29:30 | FromDiscord | <hawkey5212> In reply to @fabric.input_output "also sometimes it's not": which is where code review comes into play. I think kapendev is complaining about bad engineers letting poor design past review, than the language itself. |

| 14:38:51 | FromDiscord | <kapendev> In reply to @fabric.input_output "also sometimes it's not": I get that, and I don't really have a source for that lol, but most of them pass the error up without even trying to deal with it. "It's your problemo, friend." And then we have exceptions again. |
| 14:41:23 | FromDiscord | <kapendev> I would remove the `?` thing from the language just to make it harder to pass the problem up. |
| 15:15:58 | FromDiscord | <hawkey5212> In reply to @kapendev "I get that, and": if "that's your preblemo, friend" is how you see errors being passed up, then I can only imagine you've been mentored by engineers that have no idea what they're doing. |

| 15:23:04 | FromDiscord | <kapendev> There are a lot of things that can be improved about Rust. I am not saying that you should never pass things up. |
| 15:25:40 | FromDiscord | <hawkey5212> there are a lot of things that can be improved in _every_ language. I think rust is proven itself as the language that has the highest quality engineering behind it, though. I can only think of 3 or 4 things about it that are arguably due to lack of engineering quality going into the project. |
| 15:28:08 | FromDiscord | <hawkey5212> the sync/async issue. const generics. async trait methods. some edge cases on module/library dependency stuff. function constraints are the ones that come to mind. |
| 15:28:47 | FromDiscord | <hawkey5212> allocations assumed to not fail. |
| 15:29:25 | FromDiscord | <hawkey5212> not treating embedded as a first class citizen. |

| 15:36:04 | FromDiscord | <kapendev> Everything is kinda vibe based when designing a language. My good version of Rust will probably not be the same as most Rust users just because I like writing C, C++ and D more. Same for Nim actually. My good version of Nim would probably have better docs 🙂↵I don't really do embedded stuff, so no idea. |
