 emily | (I guess it'd require a good amount of bookkeeping to share the right bits of memory) | 20:39:44 |
 Ralith | feasible in principle | 23:40:33 |
| Ralith | a custom vulkan loader, too | 23:41:23 |
| emily | how hard can it be | 23:43:48 |
| Ralith | mostly just tedious, I think | 23:52:03 |
| Ralith | that's why you'd have to pay me :P | 23:52:09 |

| emily | maybe we can escape bootstrapping from old pre-C++ GCCs by writing a C++ compiler in Rust instead :) | 22:23:42 |

(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 |
 @aloisw:kde.org | In reply to @emilazy:matrix.org
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 |
