Trait for sending requests from server to client

This enables bidirectional communication where the server can request actions from the client, such as sampling (LLM requests), elicitation (user input requests), and task polling (per SEP-1686).

Required Methods

fn sample<'life0, 'async_trait>( &'life0 self, params: CreateMessageParams, ) -> Pin<Box<dyn Future<Output = Result<CreateMessageResult>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Send a sampling request to the client

Returns the LLM completion result from the client.

fn elicit<'life0, 'async_trait>( &'life0 self, params: ElicitRequestParams, ) -> Pin<Box<dyn Future<Output = Result<ElicitResult>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Send an elicitation request to the client

This requests user input from the client. The request can be either form-based (structured input) or URL-based (redirect to external URL).

Returns the elicitation result with the user’s action and any submitted data.

Provided Methods

fn request<'life0, 'async_trait>( &'life0 self, method: String, params: Value, ) -> Pin<Box<dyn Future<Output = Result<Value>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Send a generic JSON-RPC request to the client.

Used by typed helpers (RequestContext::get_task_info etc.) to dispatch arbitrary request methods. The default implementation returns an error so existing custom implementations of this trait keep compiling; they only need to override this if they want to support methods beyond sample and elicit.
