| K900 | This sure smells like curl | 17:54:23 |

 kloenk | what is the current state of rust in lix? I see/know there is lix-doc. but is that something that wants to get removed (saw the consumer saying some TODO that I did not fully understand).
end question would be is it acceptable to write other features in rust or should as much as possible still be C++? | 22:34:37 |
| K900 | The problem with writing features in Rust is mostly that there's no bindings to the C++ bits | 22:37:47 |
| K900 | And the C++ bits are increasingly relying on coroutines via kj which basically don't FFI | 22:38:23 |
| K900 | So you could write things in Rust, but those things need to either expose a sync C API surface or communicate over some sort of currently-not-existent RPC mechanism | 22:39:34 |
| kloenk | raito nerdsniped me to write a new log format (like the multiline I did years ago). Kinda don't have the time for that, but wonderd if I can just forward all the data to rust and do the actuall handling of all the printing in rust | 22:42:47 |
| K900 | Will have to build some sort of RPC layer for this | 22:44:29 |
| K900 | Probably | 22:44:40 |
| kloenk | From what I remember I think I could do most stuff with just a sync C abi. but also might have changed. but sounds like in general I can look into it (should I find the time for it :)) | 22:45:39 |

 raitobezarius | blocked on ability for rustc to tell us what we need to do wrt linkage to meson | 01:02:06 |
| raitobezarius | mostly libstd relinking issues, etc. | 01:02:27 |
| raitobezarius | the same set of problems that systemd is running into afaik | 01:02:40 |
| raitobezarius | if we go any RPC way, that's akin to do nom | 01:03:22 |
| 7 Nov 2025 |
 Qyriad | we think the strat re: Rust may be to just have rustc do the final link | 23:03:21 |

 Rutile (Commentator2.0) feel free to ping | currently working on this cl: https://gerrit.lix.systems/c/lix/+/4533 (specifying remote builders using toml instead of what the actual stuff the current thingy is)
but am getting the following cryptic error message, when specifying more than one element in a list:
error: bad machine specification: failed to convert column #3 in a row: 'systemTypes = ["Arch1", "Arch2"]' to 'unsigned int'"
using systemTypes = ["Arch1"] works, but as soon as i add a second value, it throws the error above..
anyone have any clue why and how to fix this?
note: am trying to data.get<std::vector<std::string>>(...)
