Struct StreamBinding 

pub struct StreamBinding {
    ssrc: Option<Ssrc>,
    repair_ssrc: Option<Ssrc>,
    rid: Option<Rid>,
    payload_type: Option<PayloadType>,
    max_bitrate: Option<u64>,
}

Routing bridge between a negotiated media format and a physical stream.

Ties logical codec formats to the physical multiplexing identifiers (primary SSRC, repair SSRC, or simulcast RID) resolved from RTP packet headers and SDP.

Wire RTP Packet Multiplexing:
  Primary Stream:  [ RTP Header: SSRC 1000 ] ------------+
                                                         |
  RTX Repair:      [ RTP Header: SSRC 1001 ] (FID/RRID)  +--> StreamBinding
                                                         |    - SSRC: 1000
  Simulcast Layer: [ Header Ext: RID "h"   ] ------------+    - Repair SSRC: 1001
                                                              - RID: "h"
                                                              - PayloadType: 96

FID supplies repair_ssrc. RID and repaired RID associate packets through rid.

Trait Implementations

impl Clone for StreamBinding

fn clone(&self) -> StreamBinding

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StreamBinding

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

Formats the value using the given formatter.

impl Default for StreamBinding

fn default() -> StreamBinding

Returns the “default value” for a type.

impl PartialEq for StreamBinding

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