Struct MultichannelConfig 

pub struct MultichannelConfig {
    pub order: MultichannelConfigOrder,
    pub channel_count: u8,
    pub extra: Vec<u8>,
}

Decoded body of an Enhanced RTMP v2 AudioPacketType.MultichannelConfig message (enhanced-rtmp-v2.pdf §“ExAudioTagBody”). The body sits in AudioTag::body verbatim on parse; callers can lift it into this strongly-typed view via MultichannelConfig::parse and round-trip back through MultichannelConfig::encode / [AudioTag::with_multichannel_config].

Per spec the body length depends on audio_channel_order:

• Unspecified (0): 2 bytes (order, channel_count).
• Native (1): 6 bytes (order, channel_count, UI32 flags).
• Custom (2): 2 + channel_count bytes (mapping is a UI8 per channel).

Any UI8 audio_channel_order value that is not one of those three surfaces as MultichannelConfigOrder::Reserved — the parser does not invent a layout, and the build path will encode just the (order, channel_count) prefix, leaving any trailing bytes to the caller via MultichannelConfig::extra.

Fields

order: MultichannelConfigOrder

The full discriminator union from the spec table. See MultichannelConfigOrder for the shape per variant.

channel_count: u8

Number of channels in the multichannel stream. UI8 on the wire, so values 0..=255 are representable.

extra: Vec<u8>

Trailing bytes preserved verbatim when [order] is MultichannelConfigOrder::Reserved (forward-compat with future spec additions). Empty for the three recognised orders.

Implementations

impl MultichannelConfig

pub fn parse(body: &[u8]) -> Result<MultichannelConfig>

Parse the body bytes of an AudioPacketType.MultichannelConfig audio message (the bytes that sit in AudioTag::body after a successful parse_audio call). Returns Err(Error::Other) on truncation; an unrecognised audioChannelOrder does NOT trigger an error — it is preserved as MultichannelConfigOrder::Reserved and any trailing bytes flow through MultichannelConfig::extra.

pub fn encode(&self) -> Vec<u8>

Serialise to the byte layout parse consumes. The output is what AudioTag::body needs to hold when constructing an outgoing MultichannelConfig message.

Trait Implementations

impl Clone for MultichannelConfig

fn clone(&self) -> MultichannelConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MultichannelConfig

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

Formats the value using the given formatter.

impl Eq for MultichannelConfig

impl PartialEq for MultichannelConfig

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