You can now use the `json_schema_input_type` argument to specify the input type of the function to be used in the JSON schema when `mode='validation'` (the default). See the example below for more details. Attributes: func: The validator function. json_schema_input_type: The input type used to generate the appropriate JSON Schema (in validation mode). The actual input type is `Any`. Example: ```python from typing import Annotated, Union from pydantic import BaseModel, PlainValidator def validate(v: object) -> int: if not isinstance(v, (int, str)): raise ValueError(f'Expected int or str, got {type(v)}') return int(v) + 1 MyInt = Annotated[ int, PlainValidator(validate, json_schema_input_type=Union[str, int]), # (1)! ] class Model(BaseModel): a: MyInt print(Model(a='1').a) #> 2 print(Model(a=1).a) #> 2 ``` 1. In this example, we've specified the `json_schema_input_type` as `Union[str, int]` which indicates to the JSON schema generator that in validation mode, the input type for the `a` field can be either a [`str`][] or an [`int`][]. r!r"rrKr#r$rr%r&c ddlm} ||}|dtjd|||}n #|$rd}YnwxYw||j}t|jdd}|r6ttj |j}tj ||| Sttj |j}tj ||| S) Nr)PydanticSchemaGenerationError serializationc||SNrHvhs r6z=PlainValidator.__get_pydantic_core_schema__..!!A$$r8)functionr. return_schemaplainr)r*)r_rO)pydanticr^getr#wrap_serializer_function_ser_schemarPrKr/r"r r0"with_info_plain_validator_functionr2 no_info_plain_validator_function) r4r#r$r^r.r_rTr5r"s r6r7z+PlainValidator.__get_pydantic_core_schema__s? ;::::: !W[))F#JJ?..!")"9"9+"F"FMM- ! ! !

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.
