//! # Uniffi support for webidl syntax, typically from a .udl file, as described by weedle.
//!
//! This library is dedicated to parsing a string in a webidl syntax, as described by
//! weedle and with our own custom take on the attributes etc, pushing the boundaries
//! of that syntax to describe a uniffi `MetatadataGroup`.
//!
//! The output of this module is consumed by uniffi_bindgen to generate stuff.
