Struct sdl2::AudioSubsystem

pub struct AudioSubsystem { /* fields omitted */ }

Methods

impl AudioSubsystem

pub fn sdl(&self) -> Sdl

Obtain an SDL context.

impl AudioSubsystem

pub fn open_playback<'a, CB, F, D>(
    &self,
    device: D,
    spec: &AudioSpecDesired,
    get_callback: F
) -> Result<AudioDevice<CB>, String> where
    CB: AudioCallback,
    F: FnOnce(AudioSpec) -> CB,
    D: Into<Option<&'a str>>, 

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

If you want to modify the callback-owned data at a later point (for example to update its data buffer) you're likely to be interested in the AudioDevice.lock method.

pub fn open_capture<'a, CB, F, D>(
    &self,
    device: D,
    spec: &AudioSpecDesired,
    get_callback: F
) -> Result<AudioDevice<CB>, String> where
    CB: AudioCallback,
    F: FnOnce(AudioSpec) -> CB,
    D: Into<Option<&'a str>>, 

Opens a new audio device for capture (given the desired parameters and callback). Supported since SDL 2.0.5

If you want to modify the callback-owned data at a later point (for example to update its data buffer) you're likely to be interested in the AudioDevice.lock method.

pub fn open_queue<'a, Channel, D>(
    &self,
    device: D,
    spec: &AudioSpecDesired
) -> Result<AudioQueue<Channel>, String> where
    Channel: AudioFormatNum,
    D: Into<Option<&'a str>>, 

Opens a new audio device which uses queueing rather than older callback method.

pub fn current_audio_driver(&self) -> &'static str

pub fn num_audio_playback_devices(&self) -> Option<u32>

pub fn audio_playback_device_name(&self, index: u32) -> Result<String, String>
