Tell us more.

https://github.com/richvdh/renovate-cargo-git-test is an example of a Cargo project with a git dependency. Cargo.lock is out of date, and can be updated with cargo update -p empty-git-lib.

Renovate reports:

{
  "baseBranch": "main"
  "config": {
    "cargo": [
      {
        "deps": [
          {
            "currentValue": "0.1.0",
            "datasource": "crate",
            "depName": "empty-git-lib",
            "depType": "dependencies",
            "lockedVersion": "0.1.0",
            "managerData": {
              "nestedVersion": true
            },
            "packageName": "empty-git-lib",
            "skipReason": "git-dependency",
            "updates": []
          }
        ],
        "lockFiles": [
          "Cargo.lock"
        ],
        "packageFile": "Cargo.toml"
      }
    ]
  }
}

My understanding, looking at the source, is that Renovate will refuse to touch any dependency that comes from a git repo. It would be great if support could be added!

Hi,
This would also be very useful for me.

I noticed that git-dependencies are supported for poetry, perhaps the same concepts could be used here?

Planning to add support for it, being also interested by that feature (so feel free to assign the issue to me), but ideally not until #31260 is merged.
