Trait Service 

pub trait Service<R: ServiceRole>:
    Send
    + Sync
    + 'static {
    // Required methods
    fn handle_request(
        &self,
        request: R::PeerReq,
        context: RequestContext<R>,
    ) -> impl Future<Output = Result<R::Resp, McpError>> + MaybeSendFuture + '_;
    fn handle_notification(
        &self,
        notification: R::PeerNot,
        context: NotificationContext<R>,
    ) -> impl Future<Output = Result<(), McpError>> + MaybeSendFuture + '_;
    fn get_info(&self) -> R::Info;

    // Provided method
    fn supported_protocol_versions(&self) -> Cow<'static, [ProtocolVersion]> { ... }
}

Available on (crate features client or server) and non-crate feature local only.

Required Methods

fn handle_request( &self, request: R::PeerReq, context: RequestContext<R>, ) -> impl Future<Output = Result<R::Resp, McpError>> + MaybeSendFuture + '_

fn handle_notification( &self, notification: R::PeerNot, context: NotificationContext<R>, ) -> impl Future<Output = Result<(), McpError>> + MaybeSendFuture + '_

fn get_info(&self) -> R::Info

Provided Methods

fn supported_protocol_versions(&self) -> Cow<'static, [ProtocolVersion]>

The protocol versions this service can speak, bounding what initialize negotiation may agree to.

Servers normally override ServerHandler::supported_protocol_versions instead of this method; the blanket Service impl forwards to it. This method exists so the transport and handshake layers, which see only a Service, can read the list and avoid agreeing to a version the server cannot serve.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
