prompt: Your task is to convert the following English description into an ASCII tree format.
  
  app is a root directory that groups 3 subdirectories: api, app and behind-middleware.
  At the main level, 'api' contains 1 subdirectories: app.
  In nested path 'api > app', The 'app' container maintains 1 folders for code organization.
  At level 3, in directory path 'api → app → [param]', '[param]' hosts 1 folders: data.
  At level 4, in directory path 'api / app / [param] / data', 'data' houses 1 nested folders: edge.
  At level 5, in directory path 'api / app / [param] / data / edge', Inside 'edge', you'll find it has no folders inside.
  At the main level, Within 'app', you'll find 1 directories for code structure.
  Within directory hierarchy 'app > [param]', '[param]' encapsulates 2 folders: loading, rsc-fetch.
  Within directory hierarchy 'app → [param] → loading', 'loading' organizes 2 subdirectory elements: page1, page2.
  At level 4, in directory path 'app > [param] > loading > page1', The 'page1' directory is currently empty.
  At level 4, in directory path 'app > [param] > loading > page2', Inside 'page2', you'll find it holds no subdirectories at the moment.
  At level 3, in directory path 'app / [param] / rsc-fetch', 'rsc-fetch' shelters 1 subdirectory elements: edge.
  Within directory hierarchy 'app > [param] > rsc-fetch > edge', The 'edge' storage space awaits content.
  At the top level, 'behind-middleware' contains nothing at present.
  
  
  Format your response in this style:
  ```
  custom_resolve_dir
   +--testproj
   |   `--__snapshots__
   `--testproj2
       `--__snapshots__
  ```
  
  Provide your answer wrapped in <ascii_formatted> tags.
