Struct Renderer 

pub struct Renderer { /* private fields */ }

Differential terminal renderer.

Tracks the previous frame to enable efficient redrawing. The strategy is automatically reset to Diff after each render.

Implementations

impl Renderer

pub fn render( &mut self, term: &mut dyn Terminal, rendered: &Rendered, ) -> Result<()>

Write the rendered output to the terminal using the current strategy.

This implementation closely follows the original TypeScript TUI renderer:

• FirstRender: outputs all lines without clearing (assumes clean alternate screen).
• FullRedraw: clears screen + scrollback, then outputs all lines.
• Diff: computes first/last changed line, moves cursor there, and only rewrites the changed region using \x1b[2K per line.

impl Renderer

pub fn new() -> Self

Create a new renderer with no previous frame and FirstRender strategy.

pub fn set_strategy(&mut self, strategy: RenderStrategy)

Override the strategy for the next render call.

pub fn previous(&self) -> Option<&Rendered>

Access the previously rendered frame, if any.
