Fields

contributor_ssrc: Option<u32>

SSRC identifier of the contributing source represented by the stats object, as defined by RFC 3550. It is a 32-bit unsigned integer that appears in the CSRC list of any packets the relevant source contributed to.

inbound_rtp_stream_id: Option<String>

ID of the RTCInboundRtpStreamStats object representing the inbound RTP stream that this contributing source is contributing to.

packets_contributed_to: Option<u64>

Total number of RTP packets that this contributing source contributed to.

This value is incremented each time a packet is counted by RTCInboundRtpStreamStats.packetsReceived, and the packet’s CSRC list (as defined by Section 5.1 in RFC 3550) contains the SSRC identifier of this contributing source, contributorSsrc.

audio_level: Option<Float>

Present if the last received RTP packet that this source contributed to contained an RFC 6465 mixer-to-client audio level header extension.

The value of audioLevel is between 0..1 (linear), where 1.0 represents 0 dBov, 0 represents silence, and 0.5 represents approximately 6 dBSPL change in the sound pressure level from 0 dBov. The RFC 6465 header extension contains values in the range 0..127, in units of -dBov, where 127 represents silence. To convert these values to the linear 0..1 range of audioLevel, a value of 127 is converted to 0, and all other values are converted using the equation:

f(rfc6465_level) = 10^(-rfc6465_level/20)

Trait Implementations

impl Clone for RtpContributingSourceStats

fn clone(&self) -> RtpContributingSourceStats

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RtpContributingSourceStats

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RtpContributingSourceStats

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for RtpContributingSourceStats

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for RtpContributingSourceStats

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

impl Serialize for RtpContributingSourceStats

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
