Struct EndpointPoolTransport 

pub struct EndpointPoolTransport { /* private fields */ }

A round-robin endpoint pool with per-endpoint circuit state.

Read-only MCP methods may fail over to another endpoint. Mutating methods, including tools/call, are attempted once unless the request contains params._meta.idempotencyKey.

Implementations

impl EndpointPoolTransport

pub fn new(config: EndpointPoolConfig) -> Self

pub fn add_endpoint( self, name: impl Into<String>, transport: impl Transport + 'static, ) -> Self

pub fn endpoint_count(&self) -> usize

Trait Implementations

impl Transport for EndpointPoolTransport

fn send_request<'life0, 'async_trait>( &'life0 mut self, request: JsonRpcRequest, ) -> Pin<Box<dyn Future<Output = McpResult<JsonRpcResponse>> + Send + 'async_trait>>

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

Send a JSON-RPC request and wait for a response

fn send_notification<'life0, 'async_trait>( &'life0 mut self, notification: JsonRpcNotification, ) -> Pin<Box<dyn Future<Output = McpResult<()>> + Send + 'async_trait>>

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

Send a JSON-RPC notification (no response expected)

fn receive_notification<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = McpResult<Option<JsonRpcNotification>>> + Send + 'async_trait>>

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

Receive a notification from the server (non-blocking)

fn close<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = McpResult<()>> + Send + 'async_trait>>

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

Close the transport connection

fn is_connected(&self) -> bool

Check if the transport is connected

fn connection_info(&self) -> String

Get connection information for debugging

fn open_subscription<'life0, 'async_trait>( &'life0 mut self, _request: JsonRpcRequest, ) -> Pin<Box<dyn Future<Output = McpResult<ClientSubscription>> + Send + 'async_trait>>

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

Open a modern long-lived subscription stream.

fn cancel_subscription<'life0, 'life1, 'async_trait>( &'life0 mut self, _request_id: &'life1 Value, ) -> Pin<Box<dyn Future<Output = McpResult<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Cancel an open subscription. HTTP implementations close the response stream; STDIO implementations send notifications/cancelled.

fn handle_incoming_request<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = McpResult<Option<JsonRpcRequest>>> + Send + 'async_trait>>

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

Handle incoming server request (for bidirectional communication)

fn send_response<'life0, 'async_trait>( &'life0 mut self, _response: JsonRpcResponse, ) -> Pin<Box<dyn Future<Output = McpResult<()>> + Send + 'async_trait>>

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

Send response to server request (for bidirectional communication)
