supports-color 1.0.0

Detects whether a terminal supports color, and gives details about that support. It takes into account the COLOR and NO_COLOR environment variables.

This crate is a Rust port of @sindresorhus' NPM package by the same name.

Example

use supports_color::Stream;

let support = supports_color::on(Stream::stdout);
if support.has_16m {
    println!("16 million (RGB) colors are supported");
} else if support.has_256 {
    println!("256-bit colors are supported.");
} else if support.has_basic {
    println!("Only basic ANSI colors are supported.");
} else {
    println!("No color support.");
}
