Struct av_data::audiosample::ChannelMap

pub struct ChannelMap { /* private fields */ }

An ordered sequence of channels.

Implementations

impl ChannelMap

pub fn new() -> Self

Creates a new sequence of channels.

pub fn add_channel(&mut self, ch: ChannelType)

Adds a single channel to the map.

pub fn add_channels(&mut self, chs: &[ChannelType])

Adds several channels to the map in order of occurrence.

pub fn len(&self) -> usize

Returns the total number of channels of the map.

pub fn is_empty(&self) -> bool

Tells if the channel map is empty.

pub fn get_channel(&self, idx: usize) -> ChannelType

Gets the channel type for a requested index.

pub fn find_channel_id(&self, t: ChannelType) -> Option<u8>

Tries to find the position of a determined type of channel in the map.

pub fn default_map(count: usize) -> Self

Creates a default channel map.

Depending on the count value, the channel map is defined differently.

When count is 1 –> the channel map is composed by a single centered channel.

When count is 2 –> the channel map is composed by a right and a left channel respectively.

For other count values, no other implementations are given for now.

Trait Implementations

impl Clone for ChannelMap

fn clone(&self) -> ChannelMap

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ChannelMap

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

Formats the value using the given formatter.

impl Default for ChannelMap

fn default() -> ChannelMap

Returns the “default value” for a type.

impl PartialEq<ChannelMap> for ChannelMap

fn eq(&self, other: &ChannelMap) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
