Struct Remote 

pub struct Remote { /* private fields */ }

The controlling side: subscribed, per device, while bars for it are on screen, and ticking at the display’s rate while there is something to draw. With nothing to draw it parks; while a view is held it wakes only to renew a watch that has gone quiet.

Implementations

impl Remote

pub fn new( send: impl Fn(&str, LinkCommand) -> bool + Send + Sync + 'static, ) -> Arc<Self>

pub fn view(self: &Arc<Self>, target: String) -> View

Watch target’s levels until the returned View is dropped.

pub fn ask(&self, again: bool)

Ask each viewed device to send its levels, where it has not been asked since the way to it last changed, or every one with again. Cheap when nothing moved: one version read. Called when the device list changes, and by the ticker when a playing target has gone quiet.

pub fn received(&self, from: &str, frame: Frame)

Frames from from, over either path.

pub fn sample(&self, playhead_ms: u64, playing: bool) -> VizLevels

What to draw now, given where the target’s playhead is.

pub fn set_fps(&self, fps: u8)

Draw at fps: the display’s rate.

pub fn ticks(&self) -> &Wake

Bumped once per display frame while there is something to draw.
