A safe wrapper for DOM nodes that prevents layout from mutating the DOM, from letting DOM nodes //! escape, and from generally doing anything that it isn't supposed to. This is accomplished via //! a simple whitelist of allowed operations, along with some lifetime magic to prevent nodes from //! escaping. //! //! As a security wrapper is only as good as its whitelist, be careful when adding operations to //! this list. The cardinal rules are: //! //! 1. Layout is not allowed to mutate the DOM. //! //! 2. Layout is not allowed to see anything with `LayoutDom` in the name, because it could hang //! onto these objects and cause use-after-free. //! //! When implementing wrapper functions, be careful that you do not touch the borrow flags, or you //! will race and cause spurious thread failure. (Note that I do not believe these races are //! exploitable, but they'll result in brokenness nonetheless.) #![allow(unsafe_code)] mod document; mod element; mod node; mod shadow_root; pub use document::*; pub use element::*; pub use node::*; pub use shadow_root::*;
