Expand description

§return_result_from_ensure_ok query modifier

When this query is called via tcx.ensure_ok(), it returns Result<(), ErrorGuaranteed> instead of (). If the query needs to be executed, and that execution returns an error, the error result is returned to the caller.

If execution is skipped, a synthetic Ok(()) is returned, on the assumption that a query with all-green inputs must have succeeded.

Can only be applied to queries with a return value of Result<_, ErrorGuaranteed>.
