## **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.

    }

    @Override
    public int size() {
      return ImmutableMultimap.this.size();
    }

    @Override
    Multiset.Entry<K> getEntry(int index) {
      Map.Entry<K, ? extends Collection<V>> entry = map.entrySet().asList().get(index);
      return Multisets.immutableEntry(entry.getKey(), entry.getValue().size());
    }

    @Override
    boolean isPartialView() {
      return true;
    }
