Channel mapping of opus stream.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Family0

Family 0 channel mapping.

Supports mono and stereo audio.

Fields

channels: u8

The number of channels, which can be 1 (mono) or 2 (stereo).

Family1

Family 1 channel mapping.

Vorbis channel order.

Fields

channels: u8

The number of channels, which can be between 1 and 8.

table: ChannelMappingTable<8>

Channel mapping table.

Family255

Available on crate feature family255 only.

Family 255 channel mapping.

Channels are unidentified.

Fields

channels: u8

The number of channels.

table: ChannelMappingTable<255>

Channel mapping table.

Reserved

Available on crate feature family255 only.

Reserved channel mapping value was used in the stream.

Such mapping may be a future extension to the container format.

Fields

channels: u8

The number of channels.

table: ChannelMappingTable<255>

Channel mapping table.

Implementations

impl ChannelMapping

pub fn get_channel_count(&self) -> u8

Get channel count.

pub fn get_stream_count(&self) -> u8

Get stream count.

pub fn get_coupled_stream_count(&self) -> u8

Get coupled stream count.

pub fn get_mapping(&self, channel: u8) -> Option<Mapping>

Get channel mapping for given channel index.

Returns None for invalid channel indexes.

Trait Implementations

impl Debug for ChannelMapping

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

Formats the value using the given formatter.

impl PartialEq for ChannelMapping

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