vendor/anstream-0.6.15/src/lib.rs

//! **Auto-adapting [`stdout`] / [`stderr`] streams**
//!
//! *A portmanteau of "ansi stream"*
//!
//! [`AutoStream`] always accepts [ANSI escape codes](https://en.wikipedia.org/wiki/ANSI_escape_code),
//! [adapting to the user's terminal's capabilities][AutoStream].
//!
//! Benefits
//! - Allows the caller to not be concerned with the terminal's capabilities
//! - Semver safe way of passing styled text between crates as ANSI escape codes offer more
//!   compatibility than most crate APIs.
//!
//! Available styling crates:
//! - [anstyle](https://docs.rs/anstyle) for minimal runtime styling, designed to go in public APIs
//! - [owo-colors](https://docs.rs/owo-colors) for feature-rich runtime styling
//! - [color-print](https://docs.rs/color-print) for feature-rich compile-time styling
//!
//! # Example
//!
//! ```
//! #  #[cfg(feature = "auto")] {
//! use anstream::println;
//! use owo_colors::OwoColorize as _;
//!
//! // Foreground colors
//! println!("My number is {:#x}!", 10.green());
//! // Background colors
//! println!("My number is not {}!", 4.on_red());
//! # }
//! ```
//!
//! And this will correctly handle piping to a file, etc
