Enum ExternalStatus 

#[non_exhaustive]
pub enum ExternalStatus {
    Prepared,
    Validated,
    AwaitingConfirmation,
    Submitted,
    ReceivedByIntermediary,
    ReceivedByAuthority,
    Accepted,
    Rejected,
    Issued,
    NotDelivered,
    Delivered,
    Completed,
}

Fine-grained state of a request another system decides (spec §17.4).

Never collapse these into a generic “done”. New states appear whenever that system adds a step, so downstream matches need a wildcard arm.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Prepared

Payload prepared locally.

Validated

Payload validated locally.

AwaitingConfirmation

Waiting for the user’s confirmation.

Submitted

Transmitted to the first hop.

ReceivedByIntermediary

An intermediary acknowledged receipt.

ReceivedByAuthority

The deciding system acknowledged receipt.

Accepted

Accepted by the deciding system.

Rejected

Rejected by the deciding system or an intermediary.

Issued

Issued by the deciding system: a ticket, a permit, a booking.

NotDelivered

Could not be delivered to the recipient.

Delivered

Delivered to the recipient.

Completed

The whole flow is complete.

Implementations

impl ExternalStatus

pub fn is_final(self) -> bool

Returns true for states after which no further external transition is expected: Self::Rejected, Self::NotDelivered, Self::Completed.

pub fn is_transmitted(self) -> bool

Returns true once the payload has left the system, i.e. an external effect may exist.

Trait Implementations

fn clone(&self) -> Self

Returns a duplicate of the value.

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