<p>Benefits</p>
<ul>
<li>Allows the caller to not be concerned with the terminal’s capabilities</li>
<li>Semver safe way of passing styled text between crates as ANSI escape codes offer more
compatibility than most crate APIs.</li>
</ul>
<p>Available styling crates:</p>
<ul>
<li><a href="https://docs.rs/anstyle">anstyle</a> for minimal runtime styling, designed to go in public APIs</li>
<li><a href="https://docs.rs/owo-colors">owo-colors</a> for feature-rich runtime styling</li>
<li><a href="https://docs.rs/color-print">color-print</a> for feature-rich compile-time styling</li>
