#### Generische Typen

Diese Typen, die Typ-Parameter in eckigen Klammern akzeptieren, werden **generische Typen** oder **Generics** genannt.

=== "Python 3.10+"

    Sie können die eingebauten Typen als Generics verwenden (mit eckigen Klammern und Typen darin):

    * `list`
    * `tuple`
    * `set`
    * `dict`

	// ensure that v and t are interfaces
	V, _ := v.Underlying().(*types.Interface)
	T, _ := t.Underlying().(*types.Interface)
	if V == nil || T == nil {
		return nil
	}

	// Mitigations for interface comparisons and generics.
	// TODO(https://github.com/golang/go/issues/50658): Support more precise conclusion.
	if free.Has(V) || free.Has(T) {
		return nil
	}
	if f, wrongType := types.MissingMethod(V, T, false); wrongType {
		return f
	}

#### Generic types

These types that take type parameters in square brackets are called **Generic types** or **Generics**, for example:

=== "Python 3.10+"

    You can use the same builtin types as generics (with square brackets and types inside):

    * `list`
    * `tuple`
    * `set`
    * `dict`

	}

	MetricsProvider

// MetricsProvider exposes metrics (e.g. used,available space) related to a
// Volume.
type MetricsProvider interface {
	// GetMetrics returns the Metrics for the Volume. Maybe expensive for
	// some implementations.
	GetMetrics() (*Metrics, error)
}

// Metrics represents the used and available bytes of the Volume.
type Metrics struct {
	// The time at which these stats were updated.

   * value should be required because the instance is known to be present, use {@link #get()}
   * instead. For a default value of {@code null}, use {@link #orNull}.
   *
   * <p>Note about generics: The signature {@code public T or(T defaultValue)} is overly
   * restrictive. However, the ideal signature, {@code public <S super T> S or(S)}, is not legal
