RCSS: Rust-Flavored CSS Preprocessor

RCSS is a styling language bringing Rust-inspired syntax to CSS. Combining Rust's robustness with SASS-like features such as nesting and variables, it aims for cleaner, more maintainable styles. The current implementation boasts Rust-like syntax, supporting variables, nesting, and functions (currently without arguments), along with a VS Code extension for syntax highlighting. Future plans include adding support for functions with arguments, importing, a formatter, improved CSS output formatting, and better error handling and debugging tools. RCSS boasts impressive compilation speed, completing in a few hundred microseconds.
