Implementations

impl<'a> CommandBuilder<'a>

fn new( cache: &'a AnalogSignalCache, viewport: &'a Viewport, num_timestamps: &'a BigInt, view_width: f32, analog_settings: AnalogSettings, ) -> Self

fn build(self) -> AnalogDrawingCommands

fn time_at_pixel(&self, px: f64) -> u64

fn pixel_at_time(&self, time: u64) -> f32

fn query(&self, time: u64) -> CacheQueryResult

fn add_before_viewport_sample(&mut self) -> Option<f32>

Captures the most recent sample occurring before the visible viewport. This method ensures rendering continuity when a signal value extends from before the viewport into the visible area.

fn iterate_pixels(&mut self, start_px: f32, end_px: f32)

fn process_flat( &mut self, px: u32, end: u32, query: &CacheQueryResult, next_change: Option<u64>, next_query_time: &mut Option<u64>, ) -> u32

fn process_range(&mut self, px: u32, t0: u64, t1: u64)

fn add_after_viewport_sample(&mut self, end_px: f32)

Extends rendering to include the first sample occurring after the visible viewport.

fn finalize(self, before_px: Option<f32>) -> AnalogDrawingCommands
