index_of_value_in_column

Error message

index_of_value_in_column

What it means

Unimplemented agate Table method: index_of_value_in_column should return the row index of the first occurrence of a needle Value in a column (or None), but the body is a todo!() stub after the single-column extraction. Any caller aborts here.

Solutions

1. Scan the extracted column for the first agate-equal match and return its index
2. Return None when the needle is absent or the column is null-only
3. Return an unsupported error instead of todo!() in the interim

When it happens

Trigger: Thrown at crates/dbt-agate/src/table.rs:250 when the library encounters an invalid state.

Common situations: See trigger scenarios.
