<p>
Given a set of type equations, the type parameters to solve for are
the type parameters of the functions that need to be instantiated
and for which no explicit type arguments is provided.
These type parameters are called <i>bound</i> type parameters.
For instance, in the <code>dedup</code> example above, the type parameters
<code>S</code> and <code>E</code> are bound to <code>dedup</code>.

# クエリパラメータと文字列の検証 { #query-parameters-and-string-validations }

**FastAPI** ではパラメータの追加情報とバリデーションを宣言することができます。

以下のアプリケーションを例にしてみましょう:

{* ../../docs_src/query_params_str_validations/tutorial001_py310.py hl[7] *}

クエリパラメータ `q` は `str | None` 型で、`str` 型ですが `None` にもなり得ることを意味し、実際にデフォルト値は `None` なので、FastAPIはそれが必須ではないと理解します。

/// note | 備考

FastAPIは、 `q` はデフォルト値が `= None` であるため、必須ではないと理解します。

`str | None` を使うことで、エディターによるより良いサポートとエラー検出を可能にします。

`Body` 및 `Query`와 동일한 방식으로 파일과 폼의 매개변수를 생성합니다:

Everything in the `'` gets sent on the command line to JMH.

You can set benchmark parameters with `-p`:
```
gradlew -p benchmarks/ run --args 'RoundingBenchmark.round -prounder=es -prange="2000-10-01 to 2000-11-01" -pzone=America/New_York -pinterval=10d -pcount=1000000'
```

The benchmark code defines default values for the parameters so if
you leave out any out JMH will run with each default value, one after
