Struct SourceEncodingDescriptor 

pub struct SourceEncodingDescriptor {
    encoding_id: SourceEncodingId,
    source_id: PublishedSourceId,
    rid: Option<Rid>,
    primary_ssrc: Option<Ssrc>,
    repair_ssrc: Option<Ssrc>,
    max_bitrate: Option<Bitrate>,
    resolution_scale: Option<u16>,
    max_framerate: Option<u16>,
    policy_role: Option<UploadLayerPolicyRole>,
    negotiated_format: Option<MediaFormat>,
}

Room-domain description of one advertised source encoding.

This keeps policy identity separate from negotiated transport facts. RID, SSRC, bitrate and codec data are metadata that help route projection, diagnostics and recording describe the encoding. They are not substitutes for SourceEncodingId.

Fields

encoding_id: SourceEncodingId

Stable source-encoding identity used by selectors.

source_id: PublishedSourceId

Parent logical source.

rid: Option<Rid>

Negotiated RID when simulcast or layered transport exposes one.

primary_ssrc: Option<Ssrc>

Primary RTP SSRC when known from negotiation or packet observation.

repair_ssrc: Option<Ssrc>

Repair RTP SSRC such as RTX when known.

max_bitrate: Option<Bitrate>

Sender-declared bitrate ceiling for this encoding.

resolution_scale: Option<u16>

Sender-side resolution downscale advertised for this encoding.

max_framerate: Option<u16>

Sender-side frame-rate ceiling advertised for this encoding.

policy_role: Option<UploadLayerPolicyRole>

Server-defined policy role associated with this encoding.

negotiated_format: Option<MediaFormat>

Negotiated payload and codec information for this encoding.

Implementations

impl SourceEncodingDescriptor

pub fn new(parts: SourceEncodingDescriptorParts) -> Self

Creates an encoding descriptor from normalized runtime facts.

This constructor does not validate parent membership because a single encoding is not authoritative alone. PublishedSourceDescriptor::new validates the full source graph when the encoding list is assembled.

pub const fn encoding_id(&self) -> SourceEncodingId

pub const fn source_id(&self) -> PublishedSourceId

pub fn rid(&self) -> Option<&Rid>

pub const fn primary_ssrc(&self) -> Option<Ssrc>

pub const fn repair_ssrc(&self) -> Option<Ssrc>

pub const fn max_bitrate(&self) -> Option<Bitrate>

pub const fn resolution_scale(&self) -> Option<u16>

pub const fn max_framerate(&self) -> Option<u16>

pub const fn policy_role(&self) -> Option<UploadLayerPolicyRole>

pub fn negotiated_format(&self) -> Option<&MediaFormat>

Trait Implementations

impl Clone for SourceEncodingDescriptor

fn clone(&self) -> SourceEncodingDescriptor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SourceEncodingDescriptor

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

Formats the value using the given formatter.

impl PartialEq for SourceEncodingDescriptor

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