Enum JsonRpcWireMessage 

pub enum JsonRpcWireMessage {
    Request(JsonRpcRequest),
    Notification(JsonRpcNotification),
    Response(JsonRpcResponse),
}

Core MCP protocol types and error handling Any single JSON-RPC 2.0 message read off the wire, in either direction.

The Response arm carries a JsonRpcResponse, which is itself the §5 Success | Error union — so one variant covers both response kinds.

Serialization is untagged: a frame serializes to the bare message object, not an externally-tagged wrapper. Parse incoming bytes with parse_json_rpc_wire_message; it validates structure rather than relying on #[serde(untagged)] deserialization, which would silently misclassify a malformed-id request as a notification.

Variants

Request(JsonRpcRequest)

A request: has a method and an id, expects a response.

Notification(JsonRpcNotification)

A notification: has a method, no id, expects no response.

Response(JsonRpcResponse)

A response to a previously-sent request (success or error).
