public protocol DataTypeProtocol

Data types tell the framework which kind of data can be parsed in the expressions

  • If the framework meets with some static value that hasn’t been processed before, it tries to convert it with every registered data type. This method returns nil if the conversion could not have been processed with any of the type’s literals.

    Parameters

    input

    Any value that is a valid DataType
