Struct MetaDef 

pub struct MetaDef {
    pub name: String,
    pub ctx: Value,
}

Named, multi-step-shared declarative context payload (GH #21 Phase 2).

Lives in the Blueprint::metas pool and is referenced by name from two independent consumers: a $step_meta.ref envelope embedded in a Step’s evaluated in value (the Step tier, resolved by EngineDispatcher::dispatch in the mlua-swarm core crate at dispatch time — see EngineDispatcher::with_step_metas), and AgentMeta::meta_ref (the Agent tier, resolved at launch time and merged UNDER the agent’s inline AgentMeta::ctx). The pool lets multiple Steps and/or Agents share one declarative context object by name instead of repeating it inline.

Fields

name: String

Logical name (= referenced by $step_meta.ref and AgentMeta.meta_ref; unique within Blueprint::metas).

ctx: Value

Declarative context payload. Consumers expect a JSON Object so it can be shallow-merged with an inline override / an agent’s own ctx (a non-Object value is rejected — loudly at dispatch time for the Step tier, defensively (warn + skip) at launch time for the Agent tier); the shape is otherwise free-form.

Trait Implementations

impl Clone for MetaDef

fn clone(&self) -> MetaDef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MetaDef

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MetaDef

fn deserialize<__D>( __deserializer: __D, ) -> Result<MetaDef, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for MetaDef

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

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 inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for MetaDef

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for MetaDef

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
