model_fields_schema

Returns a schema that matches the fields of a Pydantic model, e.g.:

from pydantic_core import SchemaValidator, core_schema

wrapper_schema = core_schema.model_fields_schema(
    {'a': core_schema.model_field(core_schema.str_schema())}
)
v = SchemaValidator(wrapper_schema)
print(v.validate_python({'a': 'hello'}))
# > ({'a': 'hello'}, None, {'a'})

    model_name: str | None = None,
    computed_fields: list[ComputedField] | None = None,
    strict: bool | None = None,
    extras_schema: CoreSchema | None = None,
    extras_keys_schema: CoreSchema | None = None,
