Fields

ssrc: u32

The SSRC these metrics describe.

loss_rate: u8

Fraction of packets lost, as 256ths.

discard_rate: u8

Fraction of packets discarded by the jitter buffer, as 256ths.

burst_density: u8

Fraction of packets lost or discarded during bursts, as 256ths.

gap_density: u8

Fraction lost or discarded during gaps between bursts, as 256ths.

burst_duration: u16

Mean burst length in milliseconds.

gap_duration: u16

Mean gap length in milliseconds.

round_trip_delay: u16

Round-trip delay in milliseconds.

end_system_delay: u16

End-system delay in milliseconds, covering encode, buffer and decode.

signal_level: u8

Signal level in dBm0.

noise_level: u8

Noise level in dBm0.

rerl: u8

Residual echo return loss, in dB.

gmin: u8

The gap threshold: consecutive received packets needed to end a burst.

rfactor: u8

The R factor, a 0–100 voice-quality estimate.

ext_rfactor: u8

An external-network R factor, for the segment beyond this one.

mos_lq: u8

Listening-quality mean opinion score, in tenths.

mos_cq: u8

Conversational-quality mean opinion score, in tenths.

rx_config: u8

Receiver configuration: packet-loss concealment and jitter-buffer flags.

reserved: u8

Reserved; sent as zero.

jb_nominal: u16

Nominal jitter-buffer delay in milliseconds.

jb_maximum: u16

Maximum jitter-buffer delay in milliseconds.

jb_abs_max: u16

The absolute maximum the jitter buffer can grow to, in milliseconds.

Implementations

impl VoIPMetricsReportBlock

pub fn xr_header(&self) -> XRHeader

The XR block header describing this block’s type and length.

Trait Implementations

impl Clone for VoIPMetricsReportBlock

fn clone(&self) -> VoIPMetricsReportBlock

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VoIPMetricsReportBlock

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

Formats the value using the given formatter.

impl Default for VoIPMetricsReportBlock

fn default() -> VoIPMetricsReportBlock

Returns the “default value” for a type.

impl Display for VoIPMetricsReportBlock

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

Formats the value using the given formatter.

impl Eq for VoIPMetricsReportBlock

impl Marshal for VoIPMetricsReportBlock

fn marshal_to(&self, buf: &mut [u8]) -> Result<usize>

marshal_to encodes the VoIPMetricsReportBlock in binary

fn marshal(&self) -> Result<BytesMut, Error>

Encodes into a freshly allocated buffer sized by MarshalSize::marshal_size.

impl MarshalSize for VoIPMetricsReportBlock

fn marshal_size(&self) -> usize

The number of bytes Marshal::marshal_to will write for this value.

impl Packet for VoIPMetricsReportBlock

fn destination_ssrc(&self) -> Vec<u32>

destination_ssrc returns an array of ssrc values that this report block refers to.

fn header(&self) -> Header

This packet’s RTCP header.

fn raw_size(&self) -> usize

The encoded size in bytes, header and padding included.

fn as_any(&self) -> &dyn Any

Downcasting hook, so a caller holding Box<dyn Packet> can recover the concrete type.

fn equal(&self, other: &dyn Packet) -> bool

Compares against another packet, since PartialEq is not object safe.

fn cloned(&self) -> Box<dyn Packet>

Clones this packet behind a trait object, since Clone is not object safe.

impl PartialEq for VoIPMetricsReportBlock

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

Equality operator ==.

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

Inequality operator !=.

impl StructuralPartialEq for VoIPMetricsReportBlock

impl Unmarshal for VoIPMetricsReportBlock

fn unmarshal<B>(raw_packet: &mut B) -> Result<Self>

where Self: Sized, B: Buf,

Unmarshal decodes the VoIPMetricsReportBlock from binary
