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: mapping_interaction_handler.rb
    path of file: ./repos/sshkit/lib/sshkit
    
    the code of the file until where you have to start completion: module SSHKit

  class MappingInteractionHandler

    def initialize(map
    
    def initialize(mapping, log_level=nil)
      @log_level = log_level
      @mapping_proc = \
        case mapping
        when Hash
          lambda do |server_output|
            first_matching_key_value = mapping.find { |k, _v| k === server_output }
            first_matching_key_value.nil? ? nil : first_matching_key_value.last
          end
        when Proc
          mapping
        else
          raise "Unsupported mapping type: #{mapping.class} - only Hash and Proc mappings are supported"
        end
