**FastAPI**는 모두 Pydantic에 기반을 두고 있습니다.

이 모든 것은 [자습서 - 사용자 안내서](tutorial/index.md)에서 실제로 많이 보게 될 것입니다.

## 메타데이터 애너테이션이 있는 타입 힌트 { #type-hints-with-metadata-annotations }

파이썬에는 `Annotated`를 사용해 이러한 타입 힌트에 **추가 <dfn title="데이터에 대한 데이터, 여기서는 타입에 대한 정보(예: 설명)">메타데이터</dfn>**를 넣을 수 있는 기능도 있습니다.

    /** Suffix for Fess crawler user agent string with bot information URL. */
    public static final String CRAWLING_USER_AGENT_SUFFIX = "; +http://fess.codelibs.org/bot.html)";

    /** Date format pattern for document index suffix generation. */
    public static final String DOCUMENT_INDEX_SUFFIX_PATTERN = "yyyyMMddHHmmssSSS";

    // ============================================================
    // System Property Keys

      }
      int[] sortedCounts = new int[sortedElements.length];
      for (int i = 0; i < length; i++) {
        int index = Arrays.binarySearch(sortedElements, 0, uniques, elements[i], comparator);
        if (counts[i] >= 0) {
          sortedCounts[index] += counts[i];
        } else {
          sortedCounts[index] = ~counts[i];
        }
      }

Aun así, en ambas situaciones, es probable que **FastAPI** [siga siendo más rápida](index.md#performance) que (o al menos comparable a) tu framework anterior.

### Dependencias { #dependencies }

Lo mismo aplica para las [dependencias](tutorial/dependencies/index.md). Si una dependencia es una función estándar `def` en lugar de `async def`, se ejecuta en el threadpool externo.
