## REST API call to plugin

To verify the custom token presented in the `AssumeRoleWithCustomToken` API, MinIO makes a POST request to the configured identity management plugin endpoint and expects a response with some details as shown below:

		Nickname string
		Age      uint
	}
	var res result
	DB.Table("users").Where("name = ?", user.Name).MapColumns(map[string]string{"name": "nickname"}).Scan(&res)
	if res.Nickname != user.Name {
		t.Errorf("Expected res.Nickname to be %s, but got %s", user.Name, res.Nickname)
	}
	if res.Name != "" {
		t.Errorf("Expected res.Name to be empty, but got %s", res.Name)
	}
	if res.Age != user.Age {

You can create production applications with **FastAPI** right now (and you have probably been doing it for some time), you just have to make sure that you use a version that works correctly with the rest of your code.

## Pin your `fastapi` version { #pin-your-fastapi-version }

	intV, ok1i := v.ToInt()
	intA, ok2i := a.ToInt()
	switch {
	case ok1i && ok2i:
		res, err := intArithOp(op, intV, intA)
		v.setInt(res)
		return err

	default:
		// Convert arguments to float
		flV, _ := v.ToFloat()
		flA, _ := a.ToFloat()
		res, err := floatArithOp(op, flV, flA)
		v.setFloat(res)
		return err
	}
}

    return ImmutableSet.of(e1, e2, e3, e4, e5);

  @Override
  protected <E extends Comparable<? super E>> Set<E> of(
      E e1, E e2, E e3, E e4, E e5, E e6, E... rest) {
    return ImmutableSet.of(e1, e2, e3, e4, e5, e6, rest);
  }

  @Override
  protected <E extends Comparable<? super E>> Set<E> copyOf(E[] elements) {
    return ImmutableSet.copyOf(elements);
  }

  @Override

        // Write first FileBothDirectoryInfo at bufferIndex=8
        SMBUtil.writeInt4(104, buffer, 8); // NextEntryOffset to second entry
        SMBUtil.writeInt4(0, buffer, 12); // FileIndex
        // ... rest of first entry fields (zeros for simplicity)
        for (int i = 16; i < 102; i++) {
            buffer[i] = 0;
        }
        SMBUtil.writeInt4(8, buffer, 68); // FileNameLength at offset 60 from start

Sie können jetzt Produktionsanwendungen mit **FastAPI** erstellen (und das tun Sie wahrscheinlich schon seit einiger Zeit), Sie müssen nur sicherstellen, dass Sie eine Version verwenden, die korrekt mit dem Rest Ihres Codes funktioniert.

## Ihre `fastapi`-Version pinnen { #pin-your-fastapi-version }

		username := userDNToUsernameMap[userDistName]
		groups, err := l.LDAP.SearchForUserGroups(conn, username, userDistName)
		if err != nil {
			return nil, err
		}
		res[userDistName] = set.CreateStringSet(groups...)
	}

	return res, nil
}

## Description of `xl.meta`

`xl.meta` is a new self describing backend format used by MinIO to support AWS S3 compatible versioning.
This file is the source of truth for each `version` at rest. `xl.meta` is a msgpack file serialized from a
well defined data structure. To understand `xl.meta` here are the few things to start with
