/**
 * Base interface for authorization handlers that provide authorization support.
 * 
 * AuthorizationHandlerImpl usually requires a {@link io.vertx.rxjava3.ext.web.handler.AuthenticationHandler} to be on the routing chain before it
 * or a custom handler that has previously set a {@link io.vertx.rxjava3.ext.auth.User} in the {@link io.vertx.rxjava3.ext.web.RoutingContext}
 *
 * 
 * NOTE: This class has been automatically generated from the {@link io.vertx.ext.web.handler.AuthorizationHandler original} non RX-ified interface using Vert.x codegen.
