//! Attributes this crate provides:
//!
//! - `#[privatize]` : Forces all fields in a struct/enum to be private
//! - `#[jstraceable]` : Auto-derives an implementation of `JSTraceable` for a struct in the script crate
//! - `#[derive(JSTraceable)]` : Auto-derives an implementation of `JSTraceable` for a struct in the script crate
//! - `#[must_root]` : Prevents data of the marked type from being used on the stack.
//! See the lints module for more details
//! - `#[dom_struct]` : Implies `#[privatize]`,`#[jstraceable]`, and `#[must_root]`.
//! - `#[dom_struct]` : Implies `#[privatize]`,`#[derive(JSTraceable)]`, and `#[must_root]`.
//! Use this for structs that correspond to a DOM type
