Expand description
Umbrella use-case error.
Use cases depend on multiple ports simultaneously; rather than forcing each
call site to enumerate every error leaf, UseCaseError aggregates the
three port-specific errors (plus domain errors) via #[from] conversions.
The variants preserve the original error for inspection via downcast_ref
or pattern matching.
