Struct sdl2::audio::AudioDevice

pub struct AudioDevice<CB: AudioCallback> { /* fields omitted */ }

Wraps SDL_AudioDeviceID and owns the callback data used by the audio device.

Methods

impl<CB: AudioCallback> AudioDevice<CB>

fn open_playback<F>(a: &AudioSubsystem, device: Option<&str>, spec: &AudioSpecDesired, get_callback: F) -> Result<AudioDevice<CB>, String> where F: FnOnce(AudioSpec) -> CB

Opens a new audio device given the desired parameters and callback.

fn subsystem(&self) -> &AudioSubsystem

fn status(&self) -> AudioStatus

fn pause(&self)

Pauses playback of the audio device.

fn resume(&self)

Starts playback of the audio device.

fn lock<'a>(&'a mut self) -> AudioDeviceLockGuard<'a, CB>

Locks the audio device using SDL_LockAudioDevice.

When the returned lock guard is dropped, SDL_UnlockAudioDevice is called. Use this method to read and mutate callback data.

fn close_and_get_callback(self) -> CB

Closes the audio device and saves the callback data from being dropped.

Note that simply dropping AudioDevice will close the audio device, but the callback data will be dropped.
