package provisioners
// Factory is a function type that creates a new instance of a resource
// provisioner, or returns an error if that is impossible.
type Factory func() (Interface, error)
// FactoryFixed is a helper that creates a Factory that just returns some given
// single provisioner.
//
// Unlike usual factories, the exact same instance is returned for each call
// to the factory and so this must be used in only specialized situations where
// the caller can take care to either not mutate the given provider at all
// or to mutate it in ways that will not cause unexpected behavior for others
// holding the same reference.
func FactoryFixed(p Interface) Factory {
return func() (Interface, error) {
return p, nil
}
