CLType

Casper types, i.e. types which can be stored and manipulated by smart contracts. Provides a description of the underlying data type of a CLValue.

CLValue

A Casper value, i.e. a value which can be stored and manipulated by smart contracts. It holds the underlying data as a type-erased, serialized Vec<u8> and also holds the CLType of the underlying data as a separate member. The parsed field, representing the original value, is a convenience only available when a CLValue is encoded to JSON, and can always be set to null if preferred.

• bytes A Casper serialized representation of the underlying value. For more information, reference the Serialization Standard.
