+//! Serde Serialization Framework
+//!
+//! Serde is a powerful framework that enables serialization libraries to generically serialize
+//! Rust data structures without the overhead of runtime type information. In many situations, the
+//! handshake protocol between serializers and serializees can be completely optimized away,
+//! leaving serde to perform roughly the same speed as a hand written serializer for a specific
+//! type.
