uv-dev

crates/uv-dev/ is uv's developer-tooling binary, run via cargo dev. It is not shipped to users — it lives in the workspace to keep dev-only tools type-safe and discoverable.

Subcommands

cargo dev generate-all          # Run every codegen (CLI ref, JSON schema, env vars, ...)
cargo dev generate-cli-reference
cargo dev generate-json-schema
cargo dev generate-env-vars-reference
cargo dev generate-options-reference
cargo dev wheel-metadata <wheel.whl>
cargo dev resolve [args…]
cargo dev install [args…]
cargo dev build [path]
cargo dev fetch-python
cargo dev compile <path>

The generate-* family backs the cargo dev generate-all command that has to run cleanly before merging — see .github/workflows/ci.yml's "cargo dev generate-all" job.
