prompt: Your task is to convert the following English description into an ASCII tree format.
  
  fn is a head directory that gathers 6 subdirectories. Notable ones include api, class, core among others.
  
  Let me break down the composition for you:
  
  At the top level, Inside 'api', you'll find it is unpopulated.
  In the root directory, The 'class' section has yet to be populated.
  At the top level, The 'core' container is a vacant space.
  In the root directory, The 'encoders' section has yet to be populated.
  At the main level, 'generators' contains 1 subdirectories: media-types.
  Within directory hierarchy 'generators → media-types', The 'media-types' folder has been left empty.
  Back to the top level.
  In the root directory, The 'types' repository awaits content.
  
  
  Format your response in this style:
  ```
  custom_resolve_dir
   +--testproj
   |   `--__snapshots__
   `--testproj2
       `--__snapshots__
  ```
  
  Provide your answer wrapped in <ascii_formatted> tags.
