pub struct HandlerRegistry { /* private fields */ }

Registry mapping method names to handlers.

Implementations

impl HandlerRegistry

pub fn new() -> Self

Create a new empty registry.

pub fn register<F, T, Fut>( &mut self, name: &str, response_type: ResponseType, handler: F, )

where F: Fn(T, RequestContext) -> Fut + Send + Sync + 'static, T: DeserializeOwned + Send + 'static, Fut: Future<Output = HandlerResult> + Send + 'static,

Register a method handler.

Arguments

• name - Method name
• response_type - Expected response type
• handler - Handler function that takes (T, RequestContext) and returns Result<()>

pub fn register_event(&mut self, name: &str)

Register an event (no handler, just ID assignment).

pub fn get_handler(&self, name: &str) -> Option<&dyn Handler>

Get a handler by method name.

pub fn get_handler_by_id(&self, id: u16) -> Option<&dyn Handler>

Get a handler by method ID.

pub fn get_method_name(&self, id: u16) -> Option<&str>

Get method name by ID.

pub fn get_method_id(&self, name: &str) -> Option<u16>

Get method ID by name.

pub fn get_event_id(&self, name: &str) -> Option<u16>

Get event ID by name.

pub fn get_response_type(&self, name: &str) -> Option<ResponseType>

Get response type for a method.

pub fn build_schema(&self) -> InitSchema

Build an InitSchema from the registered methods and events.

pub async fn dispatch( &self, method_id: u16, payload: &[u8], ctx: RequestContext, ) -> Result<()>

Dispatch a request to the appropriate handler.

Arguments

• method_id - Method ID from frame header
• payload - Raw payload bytes
• ctx - Request context for responding
