Struct ShedCounts 

pub struct ShedCounts {
    pub requests: u64,
    pub acks: u64,
    pub unmatched: u64,
}

A snapshot of what an endpoint has shed (see crate::Handle::shed).

Fields

requests: u64

Requests that reached a server transaction and could not be handed to the application.

Answered 503 Service Unavailable with a Retry-After, so the peer is told something true rather than left to retransmit into a queue that is still full.

acks: u64

ACKs that could not be handed over.

The serious one, and the reason these are not one number. An ACK for a 2xx has no transaction to answer — RFC 3261 §17.1.1.3 makes it a new transaction of its own, and there is no response to an ACK in SIP at all — so there is no 503 to send and nothing retransmits it after Timer H. Both ends are then in a dialog that no timer will reap unless session timers (RFC 4028) happen to be in play. A non-zero count here means calls are leaking.

unmatched: u64

Requests that matched no transaction and could not be handed over.

The peer will retransmit an unmatched INVITE, so this is the most survivable of the three — but it is still loss, and it was previously invisible.

Implementations

impl ShedCounts

pub fn any(self) -> bool

Whether anything has been shed at all.

pub fn total(self) -> u64

Everything shed, of every kind.

Trait Implementations

impl Clone for ShedCounts

fn clone(&self) -> ShedCounts

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ShedCounts

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

Formats the value using the given formatter.

impl Default for ShedCounts

fn default() -> ShedCounts

Returns the “default value” for a type.

impl PartialEq for ShedCounts

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