How to use the hologram.JsonSchemaMixin.register_field_encoders function in hologram

from dataclasses import dataclass, field
from typing import Optional

drop_lock: Lock = dbt.flags.MP_CONTEXT.Lock()


IAMDuration = NewType('IAMDuration', int)


class IAMDurationEncoder(FieldEncoder):
    @property
    def json_schema(self):
        return {'type': 'integer', 'minimum': 0, 'maximum': 65535}


JsonSchemaMixin.register_field_encoders({IAMDuration: IAMDurationEncoder()})


class RedshiftConnectionMethod(StrEnum):
    DATABASE = 'database'
    IAM = 'iam'


@dataclass

    )
    iam_duration_seconds: int = 900

raise ValidationError('Got invalid NoValue: {}'.format(value))
        return NoValue()
