## `Field` 추가 인자 { #field-additional-arguments }

Pydantic 모델과 같이 `Field()`를 사용할 때 추가적인 `examples`를 선언할 수 있습니다:

       * The following static final fields exist for performance reasons.
       *
       * In UnsignedBytesBenchmark, accessing the following objects via static final fields is the
       * fastest (more than twice as fast as the Java implementation, vs ~1.5x with non-final static
       * fields, on x86_32) under the Hotspot server compiler. The reason is obviously that the
       * non-final fields need to be reloaded inside the loop.

    // Helper method to set DfsEnumArray using reflection
    private void setDfsEnumArray(MsrpcDfsRootEnum target, netdfs.DfsEnumArray200 array) throws Exception {

在此之前，只支持使用单个示例的关键字 `example`。OpenAPI 3.1.0 仍然支持它，但它已被弃用，并不属于 JSON Schema 标准。因此，建议你把 `example` 迁移到 `examples`。🤓

## `Field` 的附加参数 { #field-additional-arguments }

在 Pydantic 模型中使用 `Field()` 时，你也可以声明额外的 `examples`：

{* ../../docs_src/schema_extra_example/tutorial002_py310.py hl[2,8:11] *}
