Expand description

The Validate trait is used in tandem with the Validatable type in order to provide deferred validation for types.

Trait Contract

Any type V which implement this trait must adhere to the following contract:

V and V::Unvalidated are byte-for-byte equivalent.
V and V::Unvalidated have equivalent Hash implementations.
V and V::Unvalidated must have equivalent Serialize and Deserialize implementation. This means that V and V:Unvalidated have equivalent serialized formats and that you can deserialize a V::Unvalidated from a V that was previously serialized.
