index_of_row

Error message

index_of_row

What it means

This method is an unimplemented stub: it panics with todo!() whenever called. It corresponds to AgateTable's Python index_of_row, which should return the zero-based position of the first row equal to the needle value (or None if absent), but the Rust port has not implemented the row-equality search yet. It fires only when dbt-core code calls index_of_row on a table before the stub is filled in.

Solutions

1. Scan rows for the first element-wise equal match and return its index
2. Return None if no row matches
3. Return an unsupported error instead of todo!() until implemented
