pub struct Device { /* private fields */ }

The multi-channel output (rodio).

Implementations

impl Device

pub fn play( &mut self, sound: &Sound, params: PlayParams, ) -> Result<Option<Channel>, String>

Device::Play: start sound on the first free channel. Ok(None) when all 64 are busy (the original returns null); Err when there is no audio output.

pub fn stop(&mut self, c: Channel)

Device::Stop.

pub fn stop_all(&mut self)

Scene::StopAll.

pub fn update(&mut self) -> Vec<Channel>

Device::Update: free the channels that finished, returning them (the end callbacks).

pub fn is_playing(&self, c: Channel) -> bool

Whether the channel is still allocated and has not finished.

pub fn is_active(&self, c: Channel) -> bool

Whether the channel is allocated and has not finished, paused or not.

pub fn active(&self) -> usize

The number of channels in use.

pub fn pause(&mut self, c: Channel)

Pause a channel. The other channels go on.

pub fn resume(&mut self, c: Channel)

Resume a paused channel.

pub fn is_paused(&self, c: Channel) -> bool

Whether the channel is paused.

pub fn position(&self, c: Channel) -> Duration

Position in the sound (wrapped for looping channels).

pub fn seek(&mut self, c: Channel, position: Duration) -> Result<(), String>

Move a channel to a position in its sound.

pub fn set_volume(&mut self, c: Channel, volume: f32)

Device::SetChannelVolume.

pub fn set_pitch(&mut self, c: Channel, semitones: f32)

Change a channel’s pitch, in semitones.

pub fn set_looping(&mut self, c: Channel, looping: bool)

Change whether a channel loops.

pub fn set_master_volume(&mut self, volume: f32)

Scales every channel.

pub fn unlock(&mut self)

Browsers start audio suspended until a user gesture; nothing to do natively.
