Struct AudioSubsystem

pub struct AudioSubsystem { /* private fields */ }

Available on crate feature dep_sdl2 only.

Implementations

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.
