Implementations

impl RequestFromClient

pub fn method(&self) -> &str

pub fn is_initialize_request(&self) -> bool

Returns true if the request is an InitializeRequest. Note: InitializeRequest has been removed from the 2026-07-28 protocol. This always returns false.

pub fn with_meta(self, meta: RequestMetaObject) -> Self

Stamps a RequestMetaObject (_meta) onto the request params.

params._meta is required on every request in the 2026-07-28 protocol, so the SDK typically builds one connection-level meta (protocol version, client capabilities, client info) and stamps it onto each outgoing request via this method. CustomRequest carries arbitrary params and is left unchanged.

pub fn meta(&self) -> Option<&RequestMetaObject>

Returns a reference to the request’s RequestMetaObject (_meta), or None for CustomRequest.

pub fn with_input_responses( self, input_responses: InputResponses, request_state: Option<String>, ) -> Result<Self, RpcError>

Fills in inputResponses and requestState to retry the request after the server answered with an input_required result (the 2026-07-28 mid-request input flow).

Only CallToolRequest, GetPromptRequest, and ReadResourceRequest accept input responses per the spec; any other variant returns an RpcError.
