Struct AppliesWhen 

pub struct AppliesWhen {
    pub graph_has_node_type: Option<Vec<String>>,
    pub graph_has_property: Option<GraphPropertyCheck>,
    pub tool_registered: Option<String>,
    pub extension_enabled: Option<String>,
}

The parsed shape of a SKILL.md’s applies_when: block. Each field is one predicate; None means “this predicate is not applied”. All populated fields are ANDed.

Adding a new predicate requires extending this struct and the matching arm in [Registry::evaluate_clause]. The bounded-set design is intentional — operators get type-checked semantics instead of an open-ended DSL.

Fields

graph_has_node_type: Option<Vec<String>>

Active when the running graph has any of the listed node types in its schema. Domain predicate — evaluated via the consumer’s SkillPredicateEvaluator.

graph_has_property: Option<GraphPropertyCheck>

Active when the running graph has the named property on the named node type. Domain predicate — evaluated via the consumer’s SkillPredicateEvaluator.

tool_registered: Option<String>

Active when the named tool is in the registered catalogue at boot. Framework-internal — dispatched against server.tool_router without consulting any evaluator.

extension_enabled: Option<String>

Active when the manifest’s extensions: block has the named key set to a truthy value (not absent, not null, not false). Framework-internal — dispatched against manifest.extensions.

Trait Implementations

impl Clone for AppliesWhen

fn clone(&self) -> AppliesWhen

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AppliesWhen

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

Formats the value using the given formatter.

impl Default for AppliesWhen

fn default() -> AppliesWhen

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for AppliesWhen

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for AppliesWhen

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