## ASGI Servers

Let's go a little deeper into the details.

FastAPI uses a standard for building Python web frameworks and servers called <abbr title="Asynchronous Server Gateway Interface">ASGI</abbr>. FastAPI is an ASGI web framework.

  private final Comparator<? super T> comparator;

  /*
   * We are currently considering the elements in buffer in the range [0, bufferSize) as candidates
   * for the top k elements. Whenever the buffer is filled, we quickselect the top k elements to the
   * range [0, k) and ignore the remaining elements.
   */
  private final @Nullable T[] buffer;
  private int bufferSize;

  /**

  }
}
```

> NOTE: You can use the `-cscopes` parameter to restrict the requested scopes, for example to `"openid,policy_role_attribute"`, being `policy_role_attribute` a client_scope / client_mapper that maps a role attribute called policy to a `policy` claim returned by Keycloak.

These credentials can now be used to perform MinIO API operations.

### Using MinIO Console

- Open MinIO URL on the browser, lets say <http://localhost:9000/>

            line.textContent = `${chars.slice(0, i)} ${percent}%`;
			if (percent>progressPercent) {
				break;
			}
        }
    }

    /**
     * Helper function for animation delays, called with `await`.
     * @param {number} time - Timeout, in ms.
     */
    _wait(time) {
        return new Promise(resolve => setTimeout(resolve, time));
    }

    /**

    }

    @Override
    public Set<K> elementSet() {
      return multimap.keySet();
    }

    @Override
    Iterator<K> elementIterator() {
      throw new AssertionError("should never be called");
    }
  }

  /** A skeleton implementation of {@link Multimap#entries()}. */
  abstract static class Entries<K extends @Nullable Object, V extends @Nullable Object>

	// "SCHILY.xattr." namespace.
	//
	// The following are semantically equivalent:
	//  h.Xattrs[key] = value
	//  h.PAXRecords["SCHILY.xattr."+key] = value
	//
	// When Writer.WriteHeader is called, the contents of Xattrs will take
	// precedence over those in PAXRecords.
	//
	// Deprecated: Use PAXRecords instead.
	Xattrs map[string]string

	// PAXRecords is a map of PAX extended header records.
	//

    // If a clear() happens close to the end of computation, one of two things should happen:
    // - computation ends first: the removal listener is called, and the cache does not contain the
    //   key/value pair
    // - clear() happens first: the removal listener is not called, and the cache contains the pair
    AtomicBoolean computationShouldWait = new AtomicBoolean();
    CountDownLatch computationLatch = new CountDownLatch(1);

But whenever you need them and go and learn them, know that you can already use them directly in **FastAPI**.

### Pydantic v1 `regex` instead of `pattern`

Before Pydantic version 2 and before FastAPI 0.100.0, the parameter was called `regex` instead of `pattern`, but it's now deprecated.

You could still see some code using it:

//// tab | Python 3.10+ Pydantic v1

```Python hl_lines="11"

    }

    @Override
    public void xsetPaging(boolean paging) {
        // Do nothing because this is unsupported on ConditionBean.
        // And it is possible that this method is called by PagingInvoker.
    }

    @Override
    public void enablePagingCountLater() {
        // nothing
    }

    @Override
    public void disablePagingCountLater() {
        // nothing
    }

 * The full range of code points is 0..0x10fffe. We can represent any of these code points with 21
 * bits.
 *
 * We split each code point into a 14-bit prefix and a 7-bit suffix. All code points with the same
 * prefix are called a 'section'. There are 128 code points per section.
 *
 * Ranges Data (32,612 bytes)
 * ==========================
 *
 * Each entry is 4 bytes, and represents a _range_ of code points that all share a common 14-bit
