+//! This crate provides low-level types for implementing Zcash specifications. When a
+//! common function defined in [the Zcash Protocol Specification] is used in multiple
+//! protocols (for example the Sapling and Orchard shielded protocols), a corresponding
+//! common type in this crate can be shared between implementations (for example by the
+//! [`sapling-crypto`] and [`orchard`] crates).
