Enum MessageCx 

pub enum MessageCx<Req: JrRequest = UntypedMessage, Notif: JrMessage = UntypedMessage> {
    Request(Req, JrRequestCx<Req::Response>),
    Notification(Notif),
}

An enum capturing an in-flight request or notification. In the case of a request, also includes the context used to respond to the request.

Type parameters allow specifying the concrete request and notification types. By default, both are UntypedMessage for dynamic dispatch. The request context’s response type matches the request’s response type.

Variants

Request(Req, JrRequestCx<Req::Response>)

Incoming request and the context where the response should be sent.

Notification(Notif)

Incoming notification.

Implementations

impl<Req: JrRequest, Notif: JrMessage> MessageCx<Req, Notif>

pub fn map<Req1, Notif1>( self, map_request: impl FnOnce(Req, JrRequestCx<Req::Response>) -> (Req1, JrRequestCx<Req1::Response>), map_notification: impl FnOnce(Notif) -> Notif1, ) -> MessageCx<Req1, Notif1>

where Req1: JrRequest<Response: Send>, Notif1: JrMessage,

Map the request and notification types to new types.

pub fn respond_with_error<Role: JrRole>( self, error: Error, cx: JrConnectionCx<Role>, ) -> Result<(), Error>

Respond to the message with an error.

If this message is a request, this error becomes the reply to the request.

If this message is a notification, the error is sent as a notification.

pub fn erase_to_json(self) -> Result<MessageCx, Error>

Convert to a JrRequestCx that expects a JSON value and which checks (dynamically) that the JSON value it receives can be converted to T.

pub fn to_untyped_message(&self) -> Result<UntypedMessage, Error>

Convert the message to an untyped message.

pub fn id(&self) -> Option<Value>

Returns the request ID if this is a request, None if notification.

pub fn method(&self) -> &str

Returns the method of the message (only available for UntypedMessage).

impl<M: JrRequest + JrNotification> MessageCx<M, M>

pub fn message(&self) -> &M

Returns the message of the message (only available for UntypedMessage).

Trait Implementations

impl<Req: Debug + JrRequest, Notif: Debug + JrMessage> Debug for MessageCx<Req, Notif>

where Req::Response: Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
