Enum MessageType 

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

Classification of a JSON-RPC 2.0 frame.

Emitted by MessageBuilder::parse_message to let callers dispatch on the three fundamental flavours of traffic in a JSON-RPC session.

Variants

Request(JsonRpcRequest)

Outbound request frame — method, params, and a numeric id.

Never produced by MessageBuilder::parse_message; reserved for code paths that construct requests via RequestBuilder and want to round-trip them through the same enum.

Response(JsonRpcResponse)

Inbound reply frame correlated with a previously-sent request via a shared numeric id. Carries either a result or an error payload (never both).

Notification(JsonRpcNotification)

Server-initiated push frame. Has a method and params like a request but no id, so it expects no reply. Examples: subscription updates, heartbeats.
