    Success,
    NoWorkersConfigured,
    AllWorkersUnreachable,
    AllCircuitsOpen,
    AllWorkersBusy,
    NoWorkersPassedHealth,
    AllWorkersFailedPreflight,

}

Reason for worker selection result.

Provides context when no worker is available, enabling informative fallback messages in the hook.

Variants

Success

Worker assigned successfully.

NoWorkersConfigured

No workers configured in workers.toml.

AllWorkersUnreachable

All workers are unreachable (failed health checks).

AllCircuitsOpen

All workers have circuits open (after repeated failures).

AllWorkersBusy

All workers are at capacity (no available slots).

NoWorkersPassedHealth

Workers were present but none passed selection health thresholds.

AllWorkersFailedPreflight

All candidate workers failed hard preflight checks.

AllWorkersFailedConvergence

All candidate workers failed repo convergence checks (repos missing/stale/failed).

NoAdmissibleWorkers(String)

Workers exist but admission was blocked by concrete capacity/preflight reasons.

NoMatchingWorkers

No workers match required tags or preferences.

NoWorkersWithRuntime(String)

No workers have the required runtime (e.g., Bun, Node).

SelectionError(String)

Internal error during selection.

AffinityPinned

Worker assigned via affinity pinning (recent successful build).

AffinityFallback

Worker assigned via last-success fallback (all others unavailable).

Trait Implementations

impl Clone for SelectionReason

fn clone(&self) -> SelectionReason

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SelectionReason

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SelectionReason

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for SelectionReason

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

Formats the value using the given formatter.

impl JsonSchema for SelectionReason

fn schema_name() -> String

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl PartialEq for SelectionReason

fn eq(&self, other: &SelectionReason) -> 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 SelectionReason

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 SelectionReason

impl StructuralPartialEq for SelectionReason
