This struct provides a namespace that defines the types used to impose user-defined constraints on values associated with command-line options. One type is defined for each scalar type defined in balcl::OptionType except for bool.

These types are aliases for function objects (functors) used to express user-defined constraints on option values. Such objects should return true if the supplied value (first argument) are deemed valid, and false otherwise. Descriptive error messages may be written to the supplied stream (second argument).
