Enum MessageKind 

pub enum MessageKind {
    Request,
    Notification,
    Result,
    Error,
}

Which of the four JSON-RPC 2.0 shapes a message is.

Resolved by decode and stored, so no later stage re-derives it. A request is a message with a method and an id; a notification is a message with a method and no id; the two reply shapes have an id and no method.

Variants

Request

method and id: expects a reply.

Notification

method and no id: no reply is ever sent.

Result

id and result.

Error

id and error.
