A simple way to get all the classes and their members from a struct

print_struct_members.md

Sometimes Structs have a number of class types each with their own members.

response = mediaconvert.create_job(job_params)

# This output exampled has been shortened a lot
# => #<struct Aws::MediaConvert::Types::CreateJobResponse job=#<struct Aws::MediaConvert::Types::Job arn="arn:aws:mediaconvert:us-west-1:<protected>:jobs/<hidden>-nedzn7", ...,  error_message=nil, id="1691778742640-nedzn7", job_template="arn:aws:mediaconvert:us-west-1:<protected>:jobTemplates/Test Job Template - no Audio", output_group_details=nil, queue="arn:aws:mediaconvert:us-west-1:<protected>:queues/Default", caption_selectors=nil, deblock_filter=nil, denoise_filter=nil, file_input="https://some-bucket.s3-eu-west-1.amazonaws.com/some-path/somehash/test%20vid%20copy%208.mp4", filter_enable=nil, filter_strength=nil, input_clippings=nil, program_number=nil, psi_control=nil, timecode_source="ZEROBASED", video_selector=#<struct Aws::MediaConvert::Types::VideoSelector, output_groups=[#<struct Aws::MediaConvert::Types::OutputGroup custom_name=nil, name="File Group", output_group_settings=#<struct Aws::MediaConvert::Types::OutputGroupSettings cmaf_group_settings=nil, dash_iso_group_settings=nil, file_group_settings=#<struct timestamp_offset=nil>, timed_metadata_insertion=nil>, status="SUBMITTED", timing=#<struct Aws::MediaConvert::Types::Timing finish_time=nil, start_time=nil, submit_time=2023-08-11 20:32:22 +0200>, user_metadata={}>>

To get a list of Classes and members you can do something like this

def print_members(obj, prefix='')
  if obj.respond_to?(:members)
    puts "#{prefix}#{obj.class}"
    obj.members.each do |member|
      puts "#{prefix}- #{member}"
      print_members(obj.send(member), "#{prefix}  ")
    end
  else
    puts "#{prefix}- #{obj.class}"
  end
end

response = mediaconvert.create_job(job_params)
print_members response

0> response = mediaconvert.create_job(job_params)
1> print_members response
