TerminalSink

heddle_cli_contract::cli::progress_render

Struct TerminalSink

pub struct TerminalSink { /* private fields */ }

Expand description

A Sink that paints a single, self-overwriting progress line.

On a TTY: \r-carriage-return redraw of one dim line, throttled to one repaint per COMMIT_TICK_INTERVAL units (plus forced repaint on phase change and on the first/last unit).
Off a TTY (piped human output): one dim line per throttled tick, no control codes.

The sink is Sync; its small amount of interior state (last painted phase + tick bookkeeping) lives behind a Mutex. Renders are cheap and infrequent relative to inc, so the lock is not on any hot path.

Implementations§

impl TerminalSink

pub fn new() -> TerminalSink

Trait Implementations§

impl Default for TerminalSink

fn default() -> TerminalSink

Returns the “default value” for a type. Read more

impl Sink for TerminalSink

fn render(&self, snap: ProgressSnapshot)

Present the given snapshot. Called on the thread that drove the update; may be called concurrently from multiple threads, so implementations must be Sync and manage their own interior state.
