Cargo Workspace Manager

A tool to manage your cargo workspace, inspired by Lerna.

  • You can list all the crates in the workspace
  • You can list all the changed crates in the workspace since the last git tag (or other git refs)
  • You can release the changed crates in the workspaces by interactively bumping their version which also bumps this crates version in other crates in the workspace if this is being used as a dependency.
  • You can publish the crates in the workspace automatically in the correct order.
