Calculate [specified][specified] and [computed values][computed] from a
tree of DOM nodes and a set of stylesheets.
[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. |
