## Overview

The service importer allows integrate other discovery technologies with the Vert.x service discovery. It maps entries from another technology to a and maps to a publication in this other technology. The importer is one side of a service discovery bridge.

      end
      raise ArgumentError, "Invalid arguments when calling close()"
    end

### - (`void`) start(vertx = nil, publisher = nil, configuration = nil, future = nil)

This method returns an undefined value.

Starts the importer.

Parameters:

- vertx (`::Vertx::Vertx`) (defaults to: `nil`) —
  the vertx instance
- publisher (`::VertxServiceDiscovery::ServicePublisher`) (defaults to: `nil`) —
  the service discovery instance
- configuration (`Hash{String => Object}`) (defaults to: `nil`) —
  the bridge configuration if any
- future (`::Vertx::Future`) (defaults to: `nil`) —
  a future on which the bridge must report the completion of the starting

Raises:

- (`ArgumentError`)
