1//! Support for Substrait simple and advanced extensions.
2//!
3//! Simple extensions describe YAML/URN-backed extension entities such as
4//! functions, types, and type variations. Advanced extensions carry
5//! `google.protobuf.Any` payloads for custom relation types, relation
6//! enhancements, and optimization hints.
7//!
8//! The registry APIs connect those protobuf payloads to text-format arguments
9//! by way of [`Explainable`] implementations.
