# Description This PR fixes a bug that occurs if you pass `rename --column` and empty list like `ls | rename -c []`. ## Before ``` > ls | rename -c [] thread 'main' panicked at 'index out of bounds: the len is 0 but the index is 0', crates\nu-command\src\filters\rename.rs:110:15 note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace ``` ## After ``` > ls | rename -c [] Error: nu:🐚:type_mismatch (link) × Type mismatch. ╭─[entry #1:1:1] 1 │ ls | rename -c [] · ─┬ · ╰── The list cannot be empty and must contain only two values: the column's name and its replacement value ╰──── ``` # User-Facing Changes _(List of all changes that impact the user experience here. This helps us keep track of breaking changes.)_ # Tests + Formatting Don't forget to add tests that cover your changes. Make sure you've run and fixed any issues with these commands: - `cargo fmt --all -- --check` to check standard code formatting (`cargo fmt --all` applies these changes) - `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used -A clippy::needless_collect` to check that you're using the standard code style - `cargo test --workspace` to check that all tests pass # After Submitting If your PR had any user-facing changes, update [the documentation](https://github.com/nushell/nushell.github.io) after the PR is merged, if necessary. This will help us keep the docs up to date.
