Struct AnimatedKitty 

pub struct AnimatedKitty { /* private fields */ }

The animated kitty surface presenter: the first frame becomes the root frame of one image, placed once, and every later surface appends a frame composed onto the previous one plus the rectangles that changed. Playback runs in the terminal: loading mode plays the frames it holds at the gap pace and waits for more, so the wire is a buffer, jitter never reaches the screen, and motion happens at the compositor’s rate rather than the client’s. An unchanged frame writes nothing.

Frames accumulate terminal-side, so every 96 frames a fresh root frame (one whole compressed transmit) goes up under the alternate id, and then the finished reel stops and is freed.

Implementations

impl AnimatedKitty

pub fn new( base: u32, frames_per_second: u32, tile_side: u32, budget: usize, ) -> Self

A presenter handing out image ids from base upward, playing at frames_per_second, tiling changed rectangles at tile_side surface pixels. Past budget damaged rectangles one whole frame wins over hundreds of edits.

pub fn repaint(&mut self)

Start a fresh reel on the next frame, for when the terminal may have lost what it was showing.

pub fn free<W: Sink>(&mut self, out: &mut W) -> Result<()>

Free both reels and start a fresh one on the next frame.

pub fn render_frame<W: Sink>( &mut self, out: &mut W, surface: &Surface, area: CellRect, ) -> Result<usize>

Write one frame’s data and return the bytes written.

Trait Implementations

impl Debug for AnimatedKitty

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
