Method: BitStruct::Vector.struct_class

Defined in:
lib/bit-struct/vector.rb

.struct_class(cl = nil) ⇒ Object

Called as a class method with a single argument in a user-defined subclass to specify a particular BitStruct class to use for each entry, instead of generating an anonymous class. Called without arguments to access the struct class, generating an anonymous one if needed. The struct_class inherits from the struct_class of the parent Vector class.
