Struct Presenter 

pub struct Presenter<W: Write> { /* private fields */ }

State-tracked ANSI presenter.

Transforms buffer diffs into minimal terminal output by tracking the current terminal state and only emitting necessary escape sequences.

Implementations

impl<W: Write> Presenter<W>

pub fn new(writer: W, capabilities: TerminalCapabilities) -> Self

Create a new presenter with the given writer and capabilities.

pub fn capabilities(&self) -> &TerminalCapabilities

Get the terminal capabilities.

pub fn present( &mut self, buffer: &Buffer, diff: &BufferDiff, ) -> Result<PresentStats>

Present a frame using the given buffer and diff.

This is the main entry point for rendering. It:

1. Begins synchronized output (if supported)
2. Emits changes based on the diff
3. Resets style and closes links
4. Ends synchronized output
5. Flushes all buffered output

pub fn present_with_pool( &mut self, buffer: &Buffer, diff: &BufferDiff, pool: Option<&GraphemePool>, links: Option<&LinkRegistry>, ) -> Result<PresentStats>

Present a frame with grapheme pool and link registry.

pub fn clear_screen(&mut self) -> Result<()>

Clear the entire screen.

pub fn clear_line(&mut self, y: u16) -> Result<()>

Clear a single line.

pub fn hide_cursor(&mut self) -> Result<()>

Hide the cursor.

pub fn show_cursor(&mut self) -> Result<()>

Show the cursor.

pub fn position_cursor(&mut self, x: u16, y: u16) -> Result<()>

Position the cursor at the specified coordinates.

pub fn reset(&mut self)

Reset the presenter state.

Useful after resize or when terminal state is unknown.

pub fn flush(&mut self) -> Result<()>

Flush any buffered output.

pub fn into_inner(self) -> Result<W, Error>

Get the inner writer (consuming the presenter).

Flushes any buffered data before returning the writer.
