0.1.7 (2025-02-21)

Features

• add message_type to MCPMessage trait (#26) (aca2336)

• implement ToMessage trait (#31) (435f18b)

  Details

  ToMessage Trait simplifies the construction of MCP messages, reducing the amount of code required:

  Example:

  Before Introducing the ToMessage trait

  async fn send_ping_request(ping_request: rust_mcp_schema::PingRequest) {
      let request_id = get_next_id();
  
      // construct a ServerMessage from the ping_request , with request_id
      let message = ServerMessage::Request(ServerJsonrpcRequest::new(
          request_id,
          RequestFromServer::ServerRequest(ServerRequest::PingRequest(ping_request)),
      ));
  
      // serialize message into a valid rpcJsonrpcMessage string
      let rpc_message_json_str = message.to_string();
  
      // send the ping request to the client
      tranport.send(rpc_message_json_str).await
  }

  After Introducing the ToMessage trait

  async fn send_ping_request(ping_request: rust_mcp_schema::PingRequest) {
       let request_id = get_next_id();
  
      // construct a ServerMessage from the ping_request , with request_id
      let message: ServerMessage = ping_request
          .to_message(request_id)
          .unwrap();
      
      // serialize message into a valid rpcJsonrpcMessage string
      let rpc_message_json_str = message.to_string();
  
      // send the ping request to the client
      tranport.send(rpc_message_json_str).await
  }

• introduce FromMessage trait (#30) (cc46100)
