Struct Silent 

pub struct Silent;

A device that plays nothing: for a backend with no sound yet, and tests.

Trait Implementations

impl Audio for Silent

fn music_playing(&self, _: Millis) -> Option<(&str, f64)>

The music sounding at now: its cue and the seconds since it really started (once its file had loaded), or None in silence: nothing asked for, a track still loading or whose file failed. Of two tracks sounding (a crossfade), the newest: the old one until the new one has loaded.

fn play(&mut self, _: &AudioFrame<'_>, _: Millis)

Plays one frame’s frame of audio at now: the volumes first, then the requests and the music commands in order. It also checks on what is still loading, so it is called every frame, with nothing to play too.

fn stop_all(&mut self)

Stops the music, the voice and the sounds started with a handle: the game has quit.

fn suspend(&mut self)

Holds everything sounding (the sounds started with a handle, the voice and the music) while the system suspends the game (SystemEvent::Suspend); sound cues played once finish. Pauses, or mutes where the backend can’t pause. A second call does nothing.

fn resume(&mut self)

Brings back what suspend held, and leaves a SoundRequest::PauseSounds pause in place. A call while not suspended does nothing.

fn voice_playing(&self, now: Millis) -> Option<&str>

The voice clip sounding at now, by its file (SoundRequest::Voice), or asked for and still loading: None once it has ended, and for a clip stopped, replaced, whose file failed or that loaded too late to be played. A clip held by suspend still sounds. None by default, for a device that plays no voices.

impl Clone for Silent

fn clone(&self) -> Silent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Silent

impl Debug for Silent

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

Formats the value using the given formatter.

impl Default for Silent
