A log-friendly command-line progress bar.
Many progress bar implementations update the progress report in place, by going back and overwriting previous output. This allows for beautiful progress displays, but becomes a problem when moving backwards is not possible, for example when writing to a pipe. This crate's progress bar never tries to modify what was printed before, so the output can be piped directly to a log file.
Add this to your Cargo.toml:
toml
[dependencies]
logbar = "0.1"
This example creates a default progress bar for a ten-step process:
rust
let bar = logbar::ProgressBar::new(10);
// first step (10%) done
bar.inc(1);
// next three steps done
bar.inc(3);
// everything done
bar.finish();
We can also customise the style of the progress bar:
rust
let style = Style::default()
.width(80) // 80 characters wide
.labels(false) // no XX% labels
.tick('↓').bar('-') // rendered as ↓---↓---↓ etc.
.indicator('█') // indicating the progress with '█' characters
;
let bar = logbar::ProgressBar::with_style(10, style);
bar.finish();
