# Description This fix changes pipelines to allow them to actually be empty. Mapping over empty pipelines gives empty pipelines. Empty pipelines immediately return `None` when iterated. This removes a some of where `Span::new(0, 0)` was coming from, though there are other cases where we still use it. # User-Facing Changes None # 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.
