[computed]: https://drafts.csswg.org/css-cascade/#computed [specified]: https://drafts.csswg.org/css-cascade/#specified In particular, this crate contains the definitions of supported properties, the code to parse them into specified values and calculate the computed values based on the specified values, as well as the code to serialize both specified and computed values. The main entry point is [`recalc_style_at`][recalc_style_at]. [recalc_style_at]: traversal/fn.recalc_style_at.html Major dependencies are the [cssparser][cssparser] and [selectors][selectors] crates.

parallel.rs Implements parallel traversal over the DOM tree. This traversal is based on Rayon, and therefore its safety is largely verified by the type system. The primary trickiness and fine print for the above relates to the thread safety of the DOM nodes themselves. Accessing a DOM element concurrently on multiple threads is actually mostly "safe", since all the mutable state is protected by an AtomicRefCell, and so we'll generally panic if something goes wrong. Still, we try to to enforce our thread invariants at compile time whenever possible. As such, TNode and TElement are not Send, so ordinary style system code cannot accidentally share them with other threads. In the parallel traversal, we explicitly invoke |unsafe { SendNode::new(n) }| to put nodes in containers that may be sent to other threads. This occurs in only a handful of places and is easy to grep for. At the time of this writing, there is no other unsafe code in the parallel traversal. 8009 100 %
