You can also use `SkipValidation[int]` as a shorthand for `Annotated[int, SkipValidation]`. This can be useful if you want to use a type annotation for documentation/IDE/type-checking purposes, and know that it is safe to skip validation for one or more of the fields. Because this converts the validation schema to `any_schema`, subsequent annotation-applied transformations may not have the expected effects. Therefore, when used, this annotation should generally be the final annotation applied to a type. rrr"cCst|tfSrO)r rrr2r2r3r}sz SkipValidation.__class_getitem__rr rr#cs:||tjfddgd}tj|tjddddS)Ncs|SrOr2)_crrr2r3rrz=SkipValidation.__get_pydantic_core_schema__..)js_annotation_functionscSrrOr2rr2r2r3rrr)metadatar)rbuild_metadata_dictr any_schemar)rrr rr2rr3r4sz+SkipValidation.__get_pydantic_core_schema__N)rrr"rr) r8r9r:r;rrr4rrr2r2r2r3rps    rr2) rerfrgrfrcrhrdrir"rj) rerfrgrfrcrmrdrir"rn) rerfrgrfrcrordrir"rp)rcrmr"r)rcrr"r)rcrr"r)rcrr"r)Pr; __future__r _annotations dataclassessys functoolsrtypesrtypingrrrrr r r pydantic_corer _core_schematyping_extensionsr rrrr! _internalrrrrannotated_handlerserrorsr version_inforinspect_validatorr* dataclass slots_truerr=rArErKrTrYr+r- _V2ValidatorrG_V2WrapValidatorr staticmethodr`r<rarbrlrorrValidatorFunctionWrapHandlerrrrrrModelAfterValidatorWithoutInfoValidationInfoModelAfterValidator_AnyModelWrapValidator_AnyModeBeforeValidator_AnyModelAfterValidatorrrrrr2r2r2r3s   $       7+$2 ,   ]       :<
