// typekind
|
|
// --------
|
|
// typekinds are all idl defined
|
|
// typekinds can be used to create user defined types
|
|
// a basetype can be specialized
|
|
// an enum-type can be defined using items
|
|
// a struct-type can be defined using fields
|
|
// a list can be defined holding a type T, where T can be any defined type
|
|
|
|
// types
|
|
// -----
|
|
// types are either:
|
|
// * idl-defined
|
|
// * basetypes
|
|
// * user-defined
|
|
// * deftype
|
|
// * enum
|
|
// * struct
|
|
// * list
|
|
// * undefined
|
|
// any defined type can be instantiated.
|
|
|
|
// Generic types
|
|
// generic typeskinds list, pair, set
|
|
// can only be used to define types
|
|
// they can not be used as types (e.g. in params, fields)
