The individual Flow Map invariants.

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.

OutcomeWithObligations

An outcome is present while obligations remain open.

Fields

obligation_count: usize

Number of open obligations.

MissingBlockingInteraction

A user-owned phase has no blocking interaction requirement (I6).

BlockingInteractionOnTerminalPhase

A terminal phase declares a blocking interaction.

BlockingInteractionOnNonUserPhase

A system- or external-owned phase declares a blocking interaction.

NonBlockingRequirementInBlockingSlot

The requirement in blocking_interaction is flagged non-blocking.

TerminalPhaseWithoutOutcome

A terminal phase has no outcome.

OutcomeOnNonTerminalPhase

A non-terminal phase carries an outcome.

DuplicateObligation

Two obligations serialize to the same stable identifier.

Fields

obligation_id: String

The repeated identifier (canonical JSON of the obligation).

UnserializableObligation

An obligation could not be serialized to derive its identifier.

UnanswerableBlockingInteraction

The blocking requirement carries a payload the user could not answer.

Fields

error: InteractionSpecError

Why the card is unanswerable.

Trait Implementations

impl Clone for InvariantViolationKind

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InvariantViolationKind

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for InvariantViolationKind

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

impl Eq for InvariantViolationKind

impl Error for InvariantViolationKind

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 InvariantViolationKind

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for InvariantViolationKind

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
