Struct PlayerController

Source
pub struct PlayerController { /* private fields */ }
Expand description

This type allows you to control the player from one thread, while rendering it on another.

Implementations§

Source§

impl PlayerController

Source

pub fn play(&self) -> bool

Start the playback.

Retuns true if started or already playing; false otherwise.

Source

pub fn is_playing(&self) -> bool

Source

pub fn stop(&mut self)

Stop the playback.

Source

pub fn set_position(&self, value: f64)

Set the playing position. In range [0.0, 1.0].

Will take effect only if a file is opened and it’s not empty.

Source

pub fn position(&self) -> f64

Get normalized pkaying position (i.e. in range [0.0, 1.0]).

Source

pub fn new_position_observer(&self) -> PositionObserver

initialize a new PositionObserver.

Source

pub fn set_tempo(&mut self, tempo: f32)

Set the tempo (in beats per minute).

Source

pub fn tempo(&self) -> Option<f32>

Get the tempo (in beats per minute).

Returns None if file is not set.

Source

pub fn set_volume(&mut self, volume: f32)

Set master volume.

Source

pub fn volume(&self) -> f32

Get master volume.

Source

pub fn duration(&self) -> Duration

Get file duration.

Source

pub fn set_file( &mut self, path: Option<impl Into<PathBuf>>, ) -> Result<(), Box<dyn Error>>

Set a MIDI file.

The parameter is Option<&str>, where Some value is actual path and None is for offloading.

Source

pub fn note_off_all(&mut self)

Send note off message for all notes (aka Panic)
