// deserializer is an interface for a type that deserializes an MaxMind DB
// data record to some other type. This exists as an alternative to the
// standard reflection API.
//
// This is fundamentally different than the Unmarshaler interface that
// several packages provide. A Deserializer will generally create the
// final struct or value rather than unmarshaling to itself.
//
// This interface and the associated unmarshaling code is EXPERIMENTAL!
// It is not currently covered by any Semantic Versioning guarantees.
// Use at your own risk.
