Struct BufferSurface 

pub struct BufferSurface { /* private fields */ }

The stateful cell-buffer presenter: writes a buffer’s cells once, then per frame only the cells that changed, inside synchronized output. Indexed and truecolor cell colors travel through verbatim, which makes this the presenter cell-plane demos drive directly and the engine behind the blocks path. A fresh or resized buffer clears and repaints everything; an unchanged frame writes nothing.

Implementations

impl BufferSurface

pub fn new() -> Self

A fresh presenter with no previous frame.

pub fn render_frame<W: Sink>( &mut self, out: &mut W, next: Buffer, ) -> Result<usize>

Write one frame of next and return the bytes written. A fresh or resized frame clears the screen and repaints every cell; a later frame repaints only the changed cells, inside synchronized output, with no clear that would erase the rest.

Trait Implementations

impl Debug for BufferSurface

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

Formats the value using the given formatter.

impl Default for BufferSurface

fn default() -> Self

Returns the “default value” for a type.
