Enum JsonRpcMessage 

pub enum JsonRpcMessage<Req = Request, Resp = Map<String, Value>, Noti = Notification> {
    Request(JsonRpcRequest<Req>),
    Response(JsonRpcResponse<Resp>),
    Notification(JsonRpcNotification<Noti>),
    Error(JsonRpcError),
}

Represents any JSON-RPC message that can be sent or received.

This enum covers all possible message types in the JSON-RPC protocol: individual requests/responses, notifications, and errors. It serves as the top-level message container for MCP communication.

Variants

Request(JsonRpcRequest<Req>)

A single request expecting a response

Response(JsonRpcResponse<Resp>)

A response to a previous request

Notification(JsonRpcNotification<Noti>)

A one-way notification (no response expected)

Error(JsonRpcError)

An error response
