Struct AdkClientHandler 

pub struct AdkClientHandler { /* private fields */ }

Available on crate features mcp and tools only.

Internal bridge between ADK’s ElicitationHandler and rmcp’s ClientHandler.

Wraps an Arc<dyn ElicitationHandler> and implements rmcp’s ClientHandler trait, advertising elicitation capabilities and delegating requests to the handler.

When the mcp-sampling feature is enabled, also accepts an optional Arc<dyn SamplingHandler> to handle sampling/createMessage requests.

Implementations

impl AdkClientHandler

pub fn new(handler: Arc<dyn ElicitationHandler>) -> AdkClientHandler

Create a new AdkClientHandler with the given elicitation handler.

pub fn with_tasks(self) -> AdkClientHandler

Declare the SEP-2663 tasks extension during the handshake.

A server decides per call whether to answer tools/call with a task, but it must not return one to a client that did not declare the extension. Without this, McpToolset::with_task_support configures a path no server will ever take.

pub fn with_resource_notification_handler( self, handler: Arc<dyn ResourceNotificationHandler>, ) -> AdkClientHandler

Set the handler for resource update and resource-list notifications.
