Struct TokenRenderer 

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

Streaming markdown-aware terminal renderer for assistant output.

Port of agent_token_renderer: bold/italic/inline code, fenced code blocks with keyword highlighting, grey thinking text, and UTF-8-safe byte-at-a-time streaming.

Implementations

impl<W: Write> TokenRenderer<W>

pub fn sink_mut(&mut self) -> &mut W

Borrows the sink, so a caller rendering into a buffer can harvest bytes without consuming the renderer.

pub fn new(sink: W, opts: RenderOptions) -> Self

Creates a renderer writing to sink with the given options.

pub fn set_capture(&mut self, capture: Option<TailCapture>)

Attaches a tail capture; output is recorded instead of written.

pub fn take_capture(&mut self) -> Option<TailCapture>

Detaches and returns the tail capture, if any.

pub fn wrote_visible_output(&self) -> bool

Returns true if any visible byte has been emitted.

pub fn last_output_newline(&self) -> bool

Returns true if the last emitted output byte was a newline.

pub fn set_in_think(&mut self, in_think: bool)

Sets thinking mode: grey text, markdown disabled.

pub fn write(&mut self, text: &str)

Streams a chunk of assistant text through the renderer.

pub fn write_bytes(&mut self, bytes: &[u8])

Streams raw bytes; UTF-8 sequences may be split across calls.

pub fn finish(&mut self)

Flushes pending state and emits the trailing blank line.

pub fn into_sink(self) -> W

Consumes the renderer and returns the sink it was writing into.

The Turbo Vision front end renders into a Vec<u8> and harvests the ANSI, rather than writing it to a terminal.

pub fn color(&mut self, seq: &str)

Emits a raw color escape, tracking whether a manual color is open.

pub fn plain(&mut self, s: &str)

Emits text verbatim, bypassing markdown but flushing pending state.

pub fn restore_text_attrs(&mut self)

Re-applies tracked text attributes after external output.

pub fn code_stream_begin(&mut self, syntax: &'static Syntax)

Enters code-block streaming mode with an explicit syntax.

pub fn code_stream_set_prefix( &mut self, prefix: Option<&str>, color: Option<&str>, )

Sets a per-line prefix (and its color) restored on repaint.

pub fn code_stream_set_upto_marker(&mut self, enabled: bool)

Enables highlighting of the literal [upto] marker in code lines.

pub fn code_stream_end(&mut self)

Ends code-block streaming mode, emitting any buffered line.

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

Formats the value using the given formatter.
