A CSS parser, transformer, and minifier written in Rust
...Built on the cssparser and selectors crates created by Mozilla and used by Firefox and Servo. These provide a solid general-purpose CSS-parsing foundation on top of which @parcel/css implements support for all specific CSS rules and properties. One of the main purposes of @parcel/css is to minify CSS to make it smaller. This includes many optimizations.
A static, type inferred and embeddable language written in Rust
...Gluon is a garbage-collected language but uses a separate heap for each executing gluon thread. This keeps each heap small, reducing the overhead of the garbage collector. Gluon is written in Rust, which guarantees thread safety. Gluon keeps the same guarantees, allowing multiple gluon programs to run in parallel.
