Trait DeliveryClassified 

pub trait DeliveryClassified {
    // Required method
    fn delivery_phase(&self) -> DeliveryPhase;

    // Provided method
    fn observed_status(&self) -> Option<StatusCode> { ... }
}

Error whose furthest possible request-delivery phase is explicit.

Implementations should retain a final response status once observed so authentication and reconciliation policy can classify later failures.

Required Methods

fn delivery_phase(&self) -> DeliveryPhase

Returns the conservative delivery phase for permit transitions.

Provided Methods

fn observed_status(&self) -> Option<StatusCode>

Returns a valid final status observed before the failure, when known.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
