Enum Reliability 

pub enum Reliability {
    Forbidden,
    Permitted,
    Required,
    Refuse,
}

What a UAS must do about reliability for an incoming request.

Variants

Forbidden

The peer said nothing about 100rel. §3: the UAS “MUST NOT send the provisional response reliably” — a peer that has not asked for RSeq will not send PRACK, and the response would be retransmitted for 32 seconds and then fail the invitation.

Permitted

The peer supports it. Reliable provisionals are allowed, not required.

Required

The peer put it in Require. Provisionals must be reliable.

Refuse

The peer requires it and this side will not: refuse with 420 Bad Extension and an Unsupported: 100rel (§3).

Trait Implementations

impl Clone for Reliability

fn clone(&self) -> Reliability

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Reliability

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

Formats the value using the given formatter.

impl PartialEq for Reliability

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