This is not a browser-grade CSS parser. If you need one, use cssparser + selectors.

Since it's very simple we will start with limitations:

Limitations

• At-rules are not supported. They will be skipped during parsing.
• Property values are not parsed. In CSS like * { width: 5px } you will get a width property with a 5px value as a string.
• CDO/CDC comments are not supported.
• Parser is case sensitive. All keywords must be lowercase.
• Unicode escape, like \26, is not supported.

Features

• Selector matching support.
• The rules are sorted by specificity.
• !important parsing support.
• Has a high-level parsers and low-level, zero-allocation tokenizers.
• No unsafe.

Minimum supported Rust Version (MSRV)

This version of SimpleCSS has been verified to compile with Rust 1.65 and later.

Future versions of SimpleCSS might increase the Rust version requirement. It will not be treated as a breaking change and as such can even happen with small patch releases.

# Use the problematic dependency's name and version
cargo update -p package_name --precise 0.1.1
