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

```rust use supports_color::Stream;

let support = supportscolor::on(Stream::stdout); if support.has16m { println!("16 million (RGB) colors are supported"); } else if support.has256 { println!("256-bit colors are supported."); } else if support.hasbasic { println!("Only basic ANSI colors are supported."); } else { println!("No color support."); } ```
