Struct scribl_curves::DrawSnippet

pub struct DrawSnippet { /* fields omitted */ }

A snippet is a sequence of strokes, possibly modified by a time distortion.

This struct implements druid::Data. In particular, it is cheap to clone: most of the actual data lives behind shared references.

Implementations

impl DrawSnippet

pub fn new(strokes: StrokeSeq) -> DrawSnippet

pub fn strokes<'a>(&'a self) -> impl Iterator<Item = StrokeRef<'a>>

pub fn end_time(&self) -> Option<Time>

Returns the time at which this snippet should cease to be visible, or None if the snippet should always be visible.

pub fn with_new_lerp(&self, lerp_from: Time, lerp_to: Time) -> DrawSnippet

pub fn key_times(&self) -> &[Time]

pub fn visible_at(&self, time: Time) -> bool

Has this snippet drawn anything by time?

pub fn shifted(&self, shift: TimeDiff) -> DrawSnippet

pub fn start_time(&self) -> Time

pub fn last_draw_time(&self) -> Time

The last time at which the snippet changed.

pub fn render(&self, ctx: &mut impl RenderContext, time: Time)
