We typedef the cbit_constructor_t is a constructor that use cbit create cexpr.
We typedef the cbit_constructor_map_t is a collection of constructors that use cbit create cexpr.
We typedef the value_constructor_t is a constructor that use value create cexpr.
We typedef the value_constructor_map_t is a collection of constructors that use value create cexpr.
We typedef the operator_constructor_t is a constructor that use operator create cexpr.
We typedef the operator_constructor_map_t is a collection of constructors that use operator create cexpr.
Fields¶
