Struct ProgressIndicator 

pub struct ProgressIndicator { /* private fields */ }

Shared CLI progress renderer for measurable and indeterminate work.

• Determinate (total > 0): label [=======> ] 42%
• Indeterminate (total == 0): bouncing arrow L↔R inside the bar

Renders on stderr so stdout stays free for machine-readable output. Non-TTY: silent ticks; only [finish] prints a line.

Implementations

impl ProgressIndicator

pub fn new(label: impl Into<String>) -> Self

Start a progress indicator with label (e.g. "BM25", "semantic").

pub fn set_label(&mut self, label: impl Into<String>)

Change the stage label without finishing (shared indicator across phases).

pub fn set(&mut self, done: u64, total: u64)

Set determinate progress. total == 0 switches to indeterminate.

pub fn indeterminate(&mut self)

Switch to indeterminate (infinite bouncing arrow).

pub fn tick(&mut self)

Advance animation / redraw. Call ~10–20×/s while work runs.

pub fn finish(&mut self, msg: &str)

Clear the bar and print a final success/status line.

pub fn render_line(&self) -> String

Render the current bar line (no \r). Public for tests.

Trait Implementations
