11/14/2025, 3:55 PMDoes cargo have any mechanism to a certain transitive dependency based on OS, or some other mechanism (other than forking the library)?
One of our dependency updates just pulled in another set of libraries for redox-os support, and until we actively support that, I don't know why we would pull in this dep

11/14/2025, 3:56 PMThere are no features to disable this at the top-level dep, or even at the lower-level dep

11/14/2025, 4:09 PMYes. I verified with Claude but you can use this syntax in `Cargo.toml`:
Copy code
[target.'cfg(target_os = "windows")'.dependencies]
winapi = "0.3"
[target.'cfg(target_os = "linux")'.dependencies]
openssl = "0.10"
[target.'cfg(target_arch = "wasm32")'.dependencies]
wasm-bindgen = "0.2"fast-nail-55400

11/14/2025, 4:11 PMAs for removing a dependency, will have to think about that, these are about overriding or adding dependencies.

11/14/2025, 4:12 PMClaude doesn't see a way to exclude transitive deps.

11/14/2025, 4:13 PMRight, I knew about adding dependencies - it's the removal part I don't know

11/14/2025, 4:13 PMOther than forking and doing something like that

11/14/2025, 4:13 PMyeah I'm thinking we'd have to fork and try and upstream a change to the other project

11/14/2025, 4:13 PMWhat project is it?

11/14/2025, 4:17 PMMaybe we should just replace the dep? https://github.com/dirs-dev/dirs-rs shows it as archived.

11/14/2025, 4:18 PMI have to look how we use it, but if we use it as I think, the dep likely shouldn't exist. Just points to system directories on multiple platforms. That's nice, but, dunno - seems trivial

11/14/2025, 4:19 PMAnyways, something to investigate later - it's an aside of what Im doing

11/14/2025, 4:19 PMOverride the dependency to use this version of

11/14/2025, 4:20 PMThe upstream project has restricted the
redox_usersfast-nail-55400
11/14/2025, 4:21 PMand that version appears to be published as
0.5.0w
wide-midnight-78598
11/14/2025, 4:23 PMPretty sure that's what we're using already
wide-midnight-78598
11/14/2025, 4:23 PMstill gets pulled into our lockfile though, from what I can see
f
fast-nail-55400
11/14/2025, 4:37 PMAh and then we still have to download the dependency and decide to not build it?

wide-midnight-78598
11/14/2025, 4:39 PMAs far as I can see. But even still that redox_users transitively pulls in more stuff. So, trying to clean up cruft that has no business being there, or updated, or whatever.
I'd have to clean my cache to be sure
