 emily | (-Zbuild-std doesn't work well with our existing paradigm because we'd build it for every single application and is also unstable. but it would be a good proof-of-concept.) | 08:37:54 |
 rosssmyth | An alternative to -build-std is rustc_build_sysroot which miri uses
https://github.com/RalfJung/rustc-build-sysroot
But would require wiring it up for nixpkgs | 15:35:05 |

 John Ericson | So I think that upstream Cargo should be better and -Zbuild-std doing multiple solves is an ugly hack | 15:53:40 |
| John Ericson | but that is for "not having a sysroot" and "not treating the standard library as special" | 15:53:56 |
| John Ericson | for merely building things separately, we can still do that | 15:54:08 |
| John Ericson | I have recreated the -Zbuild-std hack by mashing together two crates2nix package sets | 15:54:22 |
| John Ericson | and even buildRustPackage could probably build a standard library sysroot more or less fine | 15:54:49 |
| John Ericson | so the purely downstream thing would be basically replacing that python script they have in the rust repo with a bunch of buildRustPackage invocations | 15:55:19 |
| John Ericson | according to the bootstrap process | 15:55:25 |

| fromtheeast710 | how can I use a toml file from within a flake?
rust = pkgs.rust-bin.fromRustupToolchainFile ''
[toolchain]
channel = "stable"
components = [ "rust-src" ]
profile = "minimal"
'';

| fromtheeast710 | I don't want another config file in my project repo :v | 05:13:04 |
 K900 | You can just not use fromRustupToolchainFile | 06:39:03 |
| K900 | And specify things manually | 06:39:07 |
| fromtheeast710 | using a config like this is more readable and allow for finer control of versions imo | 06:50:54 |
| fromtheeast710 | I'm following this blogpost | 06:51:36 |
