Enum SignallingEvent 

#[non_exhaustive]
pub enum SignallingEvent {
    Acknowledged,
    RemoteBye,

    InvalidCSeq,
    Unsupported,
    AckTimedOut,
    TransportFailed,
}

One observable transition of an SDP-free confirmed dialog.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Acknowledged

The ACK matched both dialog identity and the INVITE’s sequence number.

RemoteBye

A valid increasing BYE ended the dialog and received 200 OK.

InvalidAck

An ACK named the dialog but did not carry the INVITE’s CSeq and method.

InvalidDialog

A request did not match both tags and the Call-ID. Non-ACK requests receive 481.

InvalidCSeq

A request’s CSeq was malformed, named another method or did not increase. It receives 400 or 500 as appropriate.

Unsupported

A matched request used a method this signalling-only dialog does not implement. It receives 405 with the narrow Allow set.

AckTimedOut

Timer H expired before a valid ACK arrived.

TransportFailed

Sending a required dialog response failed because the endpoint stopped accepting it.

Trait Implementations

impl Clone for SignallingEvent

fn clone(&self) -> SignallingEvent

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SignallingEvent

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

Formats the value using the given formatter.

impl PartialEq for SignallingEvent

fn eq(&self, other: &SignallingEvent) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
