Enum MethodRole 

#[non_exhaustive]
pub enum MethodRole {
    Rpc,
    StaticChild,
    DynamicChild {
        list_method: Option<String>,
        search_method: Option<String>,
    },
}

Describes how a method participates in the activation graph.

Every method on a plugin is exactly one of three kinds:

• Rpc — a regular RPC endpoint (the default).
• StaticChild — the method returns a child activation by a static name (no lookup argument). Used by #[child]-annotated methods on hubs.
• DynamicChild { .. } — the method gates a dynamic child keyed by its argument. list_method optionally names a sibling method that enumerates available keys, and search_method optionally names a sibling method that searches keys.

This tag is consumed by downstream tooling (synapse, synapse-cc, introspection clients) to reconstruct the child graph without a separate side-table. Today’s macros emit MethodRole::Rpc for every method; IR-3 populates child roles from #[child] annotations.

Wire back-compat

Added in IR-2. Serde defaults to Rpc for pre-IR schemas. #[non_exhaustive] reserves space for future variants without breaking downstream match arms.

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.

Rpc

Method is an RPC endpoint (the default for ordinary methods).

StaticChild

Method returns a child activation by static name (no lookup arg).

DynamicChild

Method gates a dynamic child keyed by its argument.

Fields

list_method: Option<String>

Optional sibling method that lists available keys.

search_method: Option<String>

Optional sibling method that searches available keys.

Trait Implementations

impl Clone for MethodRole

fn clone(&self) -> MethodRole

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MethodRole

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

Formats the value using the given formatter.

impl Default for MethodRole

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for MethodRole

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for MethodRole

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 MethodRole

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

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 MethodRole

impl StructuralPartialEq for MethodRole
