Variants

NoMatchingTransition

No transition is declared for this (phase, trigger) pair at all — the trigger variant is semantically out of scope for the current phase. Shell callers should treat this as a hard error: firing the wrong input for the current phase is a programming mistake.

Fields

phase: MeerkatPhase

trigger: MeerkatMachineTransitionTrigger

GuardRejected

A transition is declared for this (phase, trigger) pair but every candidate transition’s guard(s) evaluated false. Typed signal that the input was rejected on state, not unrecognised. Shell callers that fire idempotently (e.g., a realtime dispatcher firing ProductTurnCommitted on every observed TurnCommitted event, expecting the DSL to drop duplicates) should treat this as a successful no-op rather than an error.

Fields

phase: MeerkatPhase

trigger: MeerkatMachineTransitionTrigger

RecoveredStateInvariantRejected

A recovered authority state violated a generated invariant before any transition was attempted.

Fields

phase: MeerkatPhase

invariant: &'static str

Trait Implementations

impl Clone for MeerkatMachineTransitionError

fn clone(&self) -> MeerkatMachineTransitionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MeerkatMachineTransitionError

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

Formats the value using the given formatter.

impl Display for MeerkatMachineTransitionError

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

Formats the value using the given formatter.

impl Eq for MeerkatMachineTransitionError

impl Error for MeerkatMachineTransitionError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for MeerkatMachineTransitionError

fn eq(&self, other: &MeerkatMachineTransitionError) -> 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.
