//! Fundamental data representation.
//!
//! This module contains the types for representing data in Materialize that all
//! layers of the stack can understand. Think of it as the _lingua franca_:
//! individual layers may use different representations internally, but they all
//! agree to use this representation at their boundaries.
//!
//! * The core value type is the [`Datum`] enum, which represents a literal value.
//! * [`Row`] extends a `Datum` horizontally, and has features for efficiently
//!   doing so.
//! * [`RelationDesc`] describes what it takes to extend a `Row` vertically, and
//!   corresponds most closely to what is returned from querying our dataflows
