Enum Received 

pub enum Received {
    Acknowledge,
    Duplicate,
    OutOfOrder,
}

What the UAC should do with a reliable provisional it has just received.

Variants

Acknowledge

In order. Acknowledge it with a PRACK.

Duplicate

A retransmission of one already seen. §4: “retransmissions of that response MUST be discarded” — and notably not re-PRACKed, so a lossy path does not turn one ringing response into a stream of PRACKs.

OutOfOrder

Out of order: a gap, so an earlier response has not arrived. §4 says such a response “MUST NOT be acknowledged with a PRACK, and MUST NOT be processed further”.

Trait Implementations

impl Clone for Received

fn clone(&self) -> Received

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Received

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

Formats the value using the given formatter.

impl PartialEq for Received

fn eq(&self, other: &Received) -> 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.
