Struct TableVirtualUserRegistry 

pub struct TableVirtualUserRegistry { /* private fields */ }

Registry for user-defined virtual table factories.

This registry stores the runtime factories that create virtual table instances. It works in conjunction with MaterializedCatalog which stores the definitions.
