Enum PlanValidationError 

pub enum PlanValidationError {
    EmptyPlan,
    DuplicateStateId {
        state_id: StateId,
    },
    MissingStateForEdge {
        missing: StateId,
    },
    CircularDependency {
        cycle: Vec<StateId>,
    },
    DanglingDependencyTag {
        state_id: StateId,
        missing_tag: Tag,
    },
}

Plan validation errors (fail-fast).

These errors are intended for plan construction time, before a run is started. They help callers distinguish malformed planner output from runtime failures that occur later inside the execution engine.

Variants

EmptyPlan

The plan contained no states.

DuplicateStateId

A state identifier appeared more than once.

Fields

state_id: StateId

Duplicated state identifier.

MissingStateForEdge

A dependency edge referenced a state that does not exist in the graph.

Fields

missing: StateId

Referenced state that could not be found.

CircularDependency

The graph contained a cycle.

Fields

cycle: Vec<StateId>

State identifiers participating in the detected cycle.

DanglingDependencyTag

Optional: if planners derive edges from tag dependencies, they may validate those too.

Fields

state_id: StateId

State whose dependency hint could not be resolved.

missing_tag: Tag

Missing tag referenced by that dependency hint.

Trait Implementations

impl Clone for PlanValidationError

fn clone(&self) -> PlanValidationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PlanValidationError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PlanValidationError

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for PlanValidationError

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

impl Serialize for PlanValidationError

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for PlanValidationError

impl StructuralPartialEq for PlanValidationError
