Struct LifeloopFailureMapper 

pub struct LifeloopFailureMapper;

Concrete FailureMapper for issue #15.

Stateless and zero-sized — instances exist only so the type participates in trait dispatch.

Implementations

impl LifeloopFailureMapper

pub fn new() -> Self

pub fn map_receipt_error( &self, err: &ReceiptError, ) -> (FailureClass, RetryClass)

Convenience: map a ReceiptError to the (failure, retry) pair a failed receipt would carry.

pub fn map_transport_error( &self, err: &TransportError, ) -> (FailureClass, RetryClass)

Convenience: map a TransportError to the (failure, retry) pair a failed receipt would carry.

pub fn map_unknown_error(&self, _err: &dyn Error) -> (FailureClass, RetryClass)

Convenience: map a generic dyn std::error::Error to a (InternalError, RetryAfterReread) pair. Used when the only thing the caller has is a boxed error.

Trait Implementations

impl Clone for LifeloopFailureMapper

fn clone(&self) -> LifeloopFailureMapper

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LifeloopFailureMapper

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for LifeloopFailureMapper

fn default() -> LifeloopFailureMapper

Returns the “default value” for a type.

impl FailureMapper for LifeloopFailureMapper

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.
