The progress bar with sane defaults that doesn't slow down your loops. Inspired by [tqdm].

toml [dependencies] zzz = { version = "0.1" }

Features

• Practical defaults
• Seamless integration with iterators and streams
  • If possible, zzz infers the target size from size_hint()
• Automagically determines and updates a good printing frequency
• Very low overhead: doesn't slow down your loop, pretty much no matter how simple the loop body. On average a ...
  • !Sync progress bar update is 4 instructions (on average, 3 CPU cycles on Skylake)
  • Sync progress bar update is also 4 instructions (on average, 38 CPU cycles on Skylake)

Cargo Features

• streams: Enables support for .progress() on async streams (futures::streams::Stream)

Usage examples

Adding a progress bar to an iterator: ```rust use zzz::ProgressBarIterExt as _;

// vvvvvvvv for _ in (0..1000).into_iter().progress() { // ... } ```

Manually creating and advancing a progress bar: ```rust use zzz::ProgressBar;

let mut pb = ProgressBar::with_target(1234); for i in 0..1234 { // ... pb.add(1); } ```
