interface RenderCallbackInterface in Drupal 10

Indicates all public methods are safe to use in render callbacks.

This should only be used when all public methods on the class are supposed to used as render callbacks or the class implements ElementInterface. If this is not the case then use TrustedCallbackInterface instead.
