Class SchemaAlias

Marks a type alias of a discriminated union shared by every namespace referring to it.

Annotating the value of a union alias with an instance generates the union under the alias name in the namespace declared by the module of the alias. The alias is declared with the type statement, or with TypeAliasType before Python 3.12. Without the marker, the union is generated as a local union in each namespace referring to it.
