Struct IncomingCall 

pub struct IncomingCall<S> { /* private fields */ }

A validated, decoded call at the user Layer boundary.

Protocol framing and lifecycle state are deliberately absent. Layers can inspect the stable metadata, application state, and decoded JSON value; a Layer that intentionally shapes parameters can replace params_mut without serializing them.

Implementations

impl<S> IncomingCall<S>

pub fn kind(&self) -> CallKind

Whether this call is a request or notification.

pub fn method(&self) -> &str

The LSP or custom method name.

pub fn request_id(&self) -> Option<&RequestId>

The JSON-RPC request ID, or None for a notification.

pub fn params(&self) -> &Value

The decoded JSON parameters.

pub fn params_mut(&mut self) -> &mut Value

Mutably borrow the decoded parameters before forwarding the call.

pub fn context(&self) -> &ServerContext

The framework context for this call.

pub fn state(&self) -> &Arc<S>

The connection’s shared application state.

pub fn handler_timeout(&self) -> Option<Duration>

The configured timeout for this request, or None for a notification.

Requests begin with the connection’s ResourcePolicy::handler_timeout. A Layer may replace it with set_handler_timeout before forwarding the call.

pub fn set_handler_timeout(&mut self, timeout: Duration)

Override the timeout applied to this request handler.

Call this synchronously before forwarding the call through Next. A zero timeout expires the request as soon as dispatch is first polled. Notifications have no response deadline, so calling this for a notification has no effect.
