Saw this backlinked in tracking 1.80 issue:
https://github.com/rust-lang/cargo/pull/14452#issuecomment-2309726000
(not sure what will happen if it gets merged, but probably nothing very good) oh this is a terrifying precedent to set | 14:31:14 |
| emily | more motivation for the Rust rework, which would mitigate the damage | 14:31:40 |
| emily | they should really really really just do some hack in the compiler | 14:32:19 |
| emily | I really don't understand why Rust settled on defaulting to the only impl of a trait if one exists | 16:11:16 |
| emily | it's such a compat hazard. Haskell doesn't do it | 16:11:26 |
| emily | I mean I assume "ergonomics" but… | 16:11:34 |

I really don't understand why Rust settled on defaulting to the only impl of a trait if one exists Same, and I guess they could even change it under the same policy that allows all these breaking changes, so that the entire cost can be paid at once. | 16:53:49 |
| emily | apparently it would break .as_ref() on Cow and stuff | 16:56:46 |
| emily | which seems like maybe bad trait design (maybe Rust needs to add functional dependencies!) | 16:56:57 |

| dre | Hey, I'm running into a problem with trying to get this rust package into nixpkgs. I have the derivation right here, using rust-overlay just fine, but it requires me to have a custom rust version. When I use the nixpkgs's default buildRustPackage, it can't seem to find ldd, which it says to install llvm-tools-preview, but I don't see a way to do that. I've been stuck on this for a while -- is there a way to declaratively add rust modules to the default environment in nixpkgs? all the documenation is for flakes | 00:04:07 |

| rosssmyth | Hello, I am new to nix and have been trying to get my config setup so that it mostly matches my Windows dev machine. I'm 95% there, but there are a couple things missing, mainly compiling some of my most commonly used programs from source. To start, I'm wondering if it is possible to override how the Helix package is built. I'm having a hard time understanding the flake, so it is unclear to me. Basically I would like to do three things:
- Compile with nightly
- Enable the "unicode-lines" feature
- Use a custom build profile/flags
Thanks.

All of them could be possible, but seem like a major pain if you want to do it "properly" (without patching).
There might be some hint in crane docs: https://crane.dev/index.html
Third one may not be possible without patching if "use custom build" means you want to add new one / change current ones defined in Cargo.toml | 16:48:56 |

| rosssmyth | Using a custom profile is essentially just a funny way of passing flags to rustc, so if I can do that it would work as well. | 18:46:29 |
| rosssmyth | I spent a bunch of time looking at the crane docs and was not able to figure it out. Maybe something with the flake overlay output? But I'm not quite sure. I spent some time poking at it during the weekend and didn't make any progress. | 18:49:29 |
| ghpzin | This could be some way of doing second thing:
helix-unwrapped = inputs.helix.packages.x86_64-linux.helix-unwrapped.overrideAttrs(old: {
cargoArtifacts = old.cargoArtifacts // { cargoExtraArgs = "--features unicode-lines"; };
cargoExtraArgs = "--features unicode-lines";
} );
probably third too or using cargoBuildCommand instead.
Not sure if works, did not build myself and not sure how you would check if feature is there.
And also after that you would need to find a way to wrap resulting helix-unwrapped

| rosssmyth | I did something similar to that before just I did not have "cargoArtifacts" attr. I'll try it when I get home. | 19:35:39 |
