**FastAPI** はすべてPydanticをベースにしています。

## **FastAPI**での型ヒント

**FastAPI** はこれらの型ヒントを利用していくつかのことを行います。

**FastAPI** では型ヒントを使って型パラメータを宣言すると以下のものが得られます:

* **エディタサポート**.
* **型チェック**.

// internal buffer only needs to be resliced.
// It returns the index where bytes should be written and whether it succeeded.
func (b *Buffer) tryGrowByReslice(n int) (int, bool) {
	if l := len(b.buf); n <= cap(b.buf)-l {
		b.buf = b.buf[:l+n]
		return l, true
	}
	return 0, false
}

// grow grows the buffer to guarantee space for n more bytes.
// It returns the index where bytes should be written.
