Module output_eq 

Utility functions for output equality comparison in queries.

These functions are designed to be used with the #[query(output_eq = ...)] attribute when the output type is Result<T, E> and E does not implement PartialEq.

Functions

ignore_err

Compare Ok values for equality, treat all Err as equal.

ok_or_invalidate

Compare only the Ok values. Returns false for any Err case, causing downstream queries to be invalidated (recomputed).
