5//! This module contains shared types and messages for use by devtools/script.
6//! The traits are here instead of in script so that the devtools crate can be
7//! modified independently of the rest of Servo.
8//!
9//! Since these types can be sent through the IPC channel and use non
10//! self-describing serializers, the `flatten`, `skip*`, `tag` and `untagged`
11//! serde annotations are not supported. Types like `serde_json::Value` aren't
12//! supported either. For JSON serialization it is preferred to use a wrapper
13//! struct in the devtools crate instead.
