## Developing

If you already cloned the [fastapi repository](https://github.com/fastapi/fastapi) and you want to deep dive in the code, here are some guidelines to set up your environment.

### Install requirements

Create a virtual environment and install the required packages with [`uv`](https://github.com/astral-sh/uv):

<div class="termy">

```console
$ uv sync --extra all

    }

    @Override
    int expectedValueCollectionSize(int defaultExpectedValues, Iterable<?> values) {
      // Only trust the size of `values` if it is a Set and therefore probably already deduplicated.
      if (values instanceof Set<?>) {
        Set<?> collection = (Set<?>) values;
        return max(defaultExpectedValues, collection.size());
      } else {
        return defaultExpectedValues;
      }
    }

    /**

  // Views

  /**
   * Returns the set of distinct elements contained in this multiset. The element set is backed by
   * the same data as the multiset, so any change to either is immediately reflected in the other.
   * The order of the elements in the element set is unspecified.
   *
   * <p>If the element set supports any removal operations, these necessarily cause <b>all</b>

                  } else {
                    cache.refresh(key);
                    value = cache.get(key);
                  }
                  result.set(index, value);
                } catch (Throwable t) {
                  result.set(index, t);
                }
                gettersComplete.countDown();
              });
      thread.start();

  }
