Progress bars are `Sync` and `Send` objects which means that they are +//! internally locked and can be passed from thread to thread. +//! +//! Additionally a `MultiProgress` utility is provided that can manage +//! rendering multiple progress bars at once (eg: from multiple threads). +//! +//! To whet your appetite, this is what this can look like: +//! +//! <img src="https://github.com/console-rs/indicatif/raw/main/screenshots/yarn.gif?raw=true" width="60%"> +//! +//! Progress bars are manually advanced and by default draw to stderr. +//! When you are done, the progress bar can be finished either visibly +//! (eg: the progress bar stays on the screen) or cleared (the progress +//! bar will be removed). +//! +//! ```rust +//! use indicatif::ProgressBar; +//! +//! let bar = ProgressBar::new(1000); +//! for _ in 0..1000 { +//! bar.inc(1); +//! // ... +//! } +//! bar.finish(); +//! ``` +//! +//! General progress bar behaviors: +//! +//! * if a non terminal is detected the progress bar will be completely +//! hidden. This makes piping programs to logfiles make sense out of +//! the box. +//! * a progress bar only starts drawing when `set_message`, `inc`, `set_position` +//! or `tick` are called. In some situations you might have to call `tick` +//! once to draw it. +//! * progress bars should be explicitly finished to reset the rendering +//! for others. Either by also clearing them or by replacing them with +//! a new message / retaining the current message. +//! * the default template renders neither message nor prefix. +//! +//! # Iterators +//! +//! Similar to [tqdm](https://github.com/tqdm/tqdm), progress bars can be +//! associated with an iterator. For example: +//! +//! ```rust +//! use indicatif::ProgressIterator; +//! +//! for _ in (0..1000).progress() { +//! // ... +//! } +//! ``` +//! +//! See the [`ProgressIterator`](trait.ProgressIterator.html) trait for more +//! methods to configure the number of elements in the iterator or change +//! the progress bar style. Indicatif also has optional support for parallel +//! iterators with [Rayon](https://github.com/rayon-rs/rayon). In your +//! `Cargo.toml`, use the "rayon" feature: +//! +//! ```toml +//! [dependencies] +//! indicatif = {version = "*", features = ["rayon"]} +//! ``` +//! +//! And then use it like this: +//! +//! ```rust,ignore +//! # extern crate rayon; +//! use indicatif::ParallelProgressIterator; +//! use rayon::iter::{ParallelIterator, IntoParallelRefIterator}; +//! +//! let v: Vec<_> = (0..100000).collect(); +//! let v2: Vec<_> = v.par_iter().progress_count(v.len() as u64).map(|i| i + 1).collect(); +//! assert_eq!(v2[0], 1); +//! ``` +//! +//! Or if you'd like to customize the progress bar: +//! +//! ```rust,ignore +//! # extern crate rayon; +//! use indicatif::{ProgressBar, ParallelProgressIterator, ProgressStyle}; +//! use rayon::iter::{ParallelIterator, IntoParallelRefIterator}; +//! +//! // Alternatively, use `ProgressBar::new().with_style()` +//! let style = ProgressStyle::default_bar(); +//! let v: Vec<_> = (0..100000).collect(); +//! let v2: Vec<_> = v.par_iter().progress_with_style(style).map(|i| i + 1).collect(); +//! assert_eq!(v2[0], 1); +//! ``` +//! +//! # Templates +//! +//! Progress bars can be styled with simple format strings similar to the +//! ones in Rust itself. The format for a placeholder is `{key:options}` +//! where the `options` part is optional. If provided the format is this: +//! +//! ```text +//! <^> for an optional alignment specification (left, center and right respectively) +//! WIDTH an optional width as positive integer +//! ! an optional exclamation mark to enable truncation +//! .STYLE an optional dot separated style string +//! /STYLE an optional dot separated alternative style string +//! ``` +//! +//! For the style component see [`Style::from_dotted_str`](https://docs.rs/console/0.7.5/console/struct.Style.html#method.from_dotted_str) +//! for more information. Indicatif uses the `console` base crate for all +//! colorization and formatting options. +//! +//! Some examples for templates: +//! +//! ```text +//! [{elapsed_precise}] {bar:40.cyan/blue} {pos:>7}/{len:7} {msg} +//! ``` +//! +//! This sets a progress bar that is 40 characters wide and has cyan +//! as primary style color and blue as alternative style color. +//! Alternative styles are currently only used for progress bars. +//! +//! Example configuration: +//! +//! ```rust +//! # use indicatif::{ProgressBar, ProgressStyle}; +//! # let bar = ProgressBar::new(0); +//! bar.set_style(ProgressStyle::with_template("[{elapsed_precise}] {bar:40.cyan/blue} {pos:>7}/{len:7} {msg}") +//! .unwrap() +//! .progress_chars("##-")); +//! ``` +//! +//! The following keys exist: +//! +//! * `bar`: renders a progress bar. By default 20 characters wide. The +//! style string is used to color the elapsed part, the alternative +//! style is used for the bar that is yet to render. +//! * `wide_bar`: like `bar` but always fills the remaining space. It should not be used with +//! `wide_msg`. +//! * `spinner`: renders the spinner (current tick string). +//! * `prefix`: renders the prefix set on the progress bar. +//! * `msg`: renders the currently set message on the progress bar. +//! * `wide_msg`: like `msg` but always fills the remaining space and truncates. It should not be used +//! with `wide_bar`. +//! * `pos`: renders the current position of the bar as integer +//! * `human_pos`: renders the current position of the bar as an integer, with commas as the +//! thousands separator. +//! * `len`: renders the amount of work to be done as an integer +//! * `human_len`: renders the total length of the bar as an integer, with commas as the thousands +//! separator. +//! * `bytes`: renders the current position of the bar as bytes. +//! * `percent`: renders the current position of the bar as a percentage of the total length. +//! * `total_bytes`: renders the total length of the bar as bytes. +//! * `elapsed_precise`: renders the elapsed time as `HH:MM:SS`. +//! * `elapsed`: renders the elapsed time as `42s`, `1m` etc. +//! * `per_sec`: renders the speed in steps per second. +//! * `bytes_per_sec`: renders the speed in bytes per second. +//! * `binary_bytes_per_sec`: renders the speed in bytes per second using +//! power-of-two units, i.e. `MiB`, `KiB`, etc. +//! * `eta_precise`: the remaining time (like `elapsed_precise`). +//! * `eta`: the remaining time (like `elapsed`). +//! * `duration_precise`: the extrapolated total duration (like `elapsed_precise`). +//! * `duration`: the extrapolated total duration time (like `elapsed`). + +//! +//! The design of the progress bar can be altered with the integrated +//! template functionality. The template can be set by changing a +//! `ProgressStyle` and attaching it to the progress bar. +//! +//! # Human Readable Formatting +//! +//!
