Struct Transition 

pub struct Transition {
    pub to_state: CreditRegistrationState,
    pub error_code: Option<CreditRegistrationErrorCode>,
    pub error_message: Option<String>,
    pub needs_admin_attention: Option<bool>,
    pub event_kind: CreditRegistrationEventKind,
    pub event_message: Option<String>,
    pub actor_user_id: Option<Uuid>,
    pub suotar_api_call_id: Option<Uuid>,

    pub next_attempt_at: Option<DateTime<Utc>>,
}

Fields

to_state: CreditRegistrationState

error_code: Option<CreditRegistrationErrorCode>

error_message: Option<String>

Scrub before passing: this is persisted.

needs_admin_attention: Option<bool>

event_kind: CreditRegistrationEventKind

event_message: Option<String>

actor_user_id: Option<Uuid>

suotar_api_call_id: Option<Uuid>

event_details: Option<Value>

Already scrubbed {request, response} payload for the event row.

expected_from_state: Option<CreditRegistrationState>

Set by a caller that computed to_state from a row snapshot taken before an await (an external call, or a gap before its own transaction) during which some other writer could have moved the row on. None skips the check, for callers writing from a snapshot taken under the same transaction’s lock.

policy: TransitionPolicy

Which (from → to) edges this write may take; see TransitionPolicy.

next_attempt_at: Option<DateTime<Utc>>

When the pipeline may claim the row next. None takes the target state’s default cadence, which is what keeps a caller that forgets from leaving the row spinning.

Implementations

impl Transition

pub fn to(to_state: CreditRegistrationState) -> Self

pub fn by_hand(to_state: CreditRegistrationState) -> Self

A move a human asked for, which may also take the ADMIN_ONLY_TARGETS edges.

pub fn planted(to_state: CreditRegistrationState) -> Self

A fixture planting a row in a state directly; see TransitionPolicy::Planted.

Trait Implementations

impl Clone for Transition

fn clone(&self) -> Transition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Transition

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

Formats the value using the given formatter.

impl PartialEq for Transition

fn eq(&self, other: &Transition) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
