What answering a SUBSCRIBE concluded.

Variants

Established

A new subscription. Answer 2xx, then send the first NOTIFY.

Fields

id: Id

Which one.

expires: Duration

The expiry granted, which may be shorter than the one asked for.

Refreshed

An existing subscription’s timer was pushed out.

Fields

id: Id

Which one.

expires: Duration

The expiry granted.

Unsubscribed

Expires: 0 — the subscriber is leaving (§3.1.1).

The notifier still owes a terminating NOTIFY (§4.2.1.4), which is the part that is easy to miss: an unsubscribe is not a subscription of no duration, it is an ending.

Fields

id: Id

Which one.

Unserved

The Event names a package this notifier does not serve. Answer [BAD_EVENT].

Fields

status: u16

The status to answer with — 489, and not 400 or 501.

AtCapacity

A new subscription would exceed this notifier’s configured peer-driven resource bound.

Malformed

The request could not be read as a SUBSCRIBE at all.

OutOfOrder

A matching subscription received an equal or lower remote CSeq.

Fields

id: Id

The subscription that was deliberately left unchanged.

Trait Implementations

impl Clone for Answer

fn clone(&self) -> Answer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Answer

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

Formats the value using the given formatter.

impl PartialEq for Answer

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