You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: commit_signature_interface.rb
    path of file: ./repos/gitlabhq/app/graphql/types
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Types
  module CommitSignatureInterface
    include Types::BaseInterface

    graphql_name 'CommitSignature'

    description 'Represents signing information for a commit'

    field :verification_status, CommitSignatures::VerificationStatusEnum,
                
    
    def self.resolve_type(object, context)
      case object
      when ::CommitSignatures::GpgSignature
        Types::CommitSignatures::GpgSignatureType
      when ::CommitSignatures::X509CommitSignature
        Types::CommitSignatures::X509SignatureType
      when ::CommitSignatures::SshSignature
        Types::CommitSignatures::SshSignatureType
      else
        raise 'Unsupported commit signature type'
      end
