Trait FailureMapper 

Source 
pub trait FailureMapper {
    // Required method
    fn map_route_error(&self, err: &RouteError) -> (FailureClass, RetryClass);
}
Expand description

Failure-class mapping seam.

A future router issue will map RouteError (and downstream stage errors) onto the FailureClass / RetryClass pair carried on a status=failed receipt. The skeleton defines the trait shape only.

Required Methods§

Source

fn map_route_error(&self, err: &RouteError) -> (FailureClass, RetryClass)

Map a RouteError to a (failure_class, retry_class) pair. Implementations must be deterministic — the same RouteError variant must always map to the same pair so receipt ledgers replay consistently.
