Indexed

def Indexed(typ=None, index_type=ASCENDING, **kwargs: Any)

If typ is defined, returns a subclass of typ with an extra attribute _indexed as a tuple: - Index 0: index_type such as pymongo.ASCENDING - Index 1: kwargs passed to IndexModel When instantiated the type of the result will actually be typ.

When typ is not defined, returns an IndexedAnnotation instance, to be used as metadata in Annotated fields.

Example:

# Both fields would have the same behavior
class MyModel(BaseModel):
    field1: Indexed(str, unique=True)
    field2: Annotated[str, Indexed(unique=True)]
