Struct Player 

pub struct Player { /* private fields */ }

Handle to a device that outputs sounds.

Dropping the Player stops all its sounds. You can use detach if you want the sounds to continue playing.

Implementations

impl Player

pub fn connect_new(mixer: &Mixer) -> Player

Builds a new Player, beginning playback on a stream.

pub fn new() -> (Player, SourcesQueueOutput)

Builds a new Player.

pub fn append<S>(&self, source: S)

where S: Source + Send + 'static, f32: FromSample<S::Item>,

Appends a sound to the queue of sounds to play.

pub fn volume(&self) -> Float

Gets the volume of the sound.

The value 1.0 is the “normal” volume (unfiltered input). Any value other than 1.0 will multiply each sample by this value.

pub fn set_volume(&self, value: Float)

Changes the volume of the sound.

The value 1.0 is the “normal” volume (unfiltered input). Any value other than 1.0 will multiply each sample by this value.

pub fn speed(&self) -> f32

Gets the speed of the sound.

See Player::set_speed for details on what speed means.

pub fn set_speed(&self, value: f32)

Changes the play speed of the sound. Does not adjust the samples, only the playback speed.

Note:

1. Increasing the speed will increase the pitch by the same factor

• If you set the speed to 0.5 this will halve the frequency of the sound lowering its pitch.
• If you set the speed to 2 the frequency will double raising the pitch of the sound.

2. Change in the speed affect the total duration inversely

• If you set the speed to 0.5, the total duration will be twice as long.
• If you set the speed to 2 the total duration will be halve of what it was.

pub fn play(&self)

Resumes playback of a paused player.

No effect if not paused.

pub fn try_seek(&self, pos: Duration) -> Result<(), SeekError>

Attempts to seek to a given position in the current source.

This blocks between 0 and ~5 milliseconds.

As long as the duration of the source is known, seek is guaranteed to saturate at the end of the source. For example given a source that reports a total duration of 42 seconds calling try_seek() with 60 seconds as argument will seek to 42 seconds.

Errors

This function will return SeekError::NotSupported if one of the underlying sources does not support seeking.

It will return an error if an implementation ran into one during the seek.

When seeking beyond the end of a source this function might return an error if the duration of the source is not known.

pub fn pause(&self)

Pauses playback of this player.

No effect if already paused.

A paused sink can be resumed with play().

pub fn is_paused(&self) -> bool

Gets if a sink is paused

Players can be paused and resumed using pause() and play(). This returns true if the sink is paused.

pub fn clear(&self)

Removes all currently loaded Sources from the Player, and pauses it.

See pause() for information about pausing a Player.

pub fn skip_one(&self)

Skips to the next Source in the Player

If there are more Sources appended to the Player at the time, it will play the next one. Otherwise, the Player will finish as if it had finished playing a Source all the way through.

pub fn stop(&self)

Stops the sink by emptying the queue.

pub fn detach(self)

Destroys the sink without stopping the sounds that are still playing.

pub fn sleep_until_end(&self)

Sleeps the current thread until the sound ends.

pub fn empty(&self) -> bool

Returns true if this sink has no more sounds to play.

pub fn len(&self) -> usize

Returns the number of sounds currently in the queue.

pub fn get_pos(&self) -> Duration

Returns the position of the sound that’s being played.

This takes into account any speedup or delay applied.

Example: if you apply a speedup of 2 to an mp3 decoder source and get_pos() returns 5s then the position in the mp3 recording is 10s from its start.

Trait Implementations

impl Drop for Player

fn drop(&mut self)

Executes the destructor for this type.
