Struct MethodSchema 

pub struct MethodSchema {
    pub name: String,
    pub description: String,
    pub hash: String,
    pub params: Option<Schema>,
    pub returns: Option<Schema>,
    pub streaming: bool,
}

Schema for a single method exposed by a plugin

Fields

name: String

Method name (e.g., “echo”, “check”)

description: String

Human-readable description of what this method does

hash: String

Content hash of the method definition (for cache invalidation) Generated by hashing the method signature within hub-macro

params: Option<Schema>

JSON Schema for the method’s parameters (None if no params)

returns: Option<Schema>

JSON Schema for the method’s return type (None if not specified)

streaming: bool

Whether this method streams multiple events (true) or returns a single result (false)

• streaming: true → returns AsyncGenerator<T> (multiple events)
• streaming: false → returns Promise<T> (single event, collected)

All methods use the same streaming protocol under the hood, but this flag tells clients how to present the result.

Implementations

impl MethodSchema

pub fn new( name: impl Into<String>, description: impl Into<String>, hash: impl Into<String>, ) -> Self

Create a new method schema with name, description, and hash

The hash should be computed from the method definition string within the hub-macro at compile time.

pub fn with_params(self, params: Schema) -> Self

Add parameter schema

pub fn with_returns(self, returns: Schema) -> Self

Add return type schema

pub fn with_streaming(self, streaming: bool) -> Self

Set the streaming flag

• true → method streams multiple events (use AsyncGenerator<T>)
• false → method returns single result (use Promise<T>)

Trait Implementations

impl Clone for MethodSchema

fn clone(&self) -> MethodSchema

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MethodSchema

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MethodSchema

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for MethodSchema

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 Serialize for MethodSchema

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
