This crate serves as an extension of prettytable by specifying a Tablefy trait in order to turn any struct (whose members implement Display) to turn into a Table object.

As a result, this means that prettytable is a dependency. You won't be able to use this crate without also adding prettytable.

If you'd like to get the full functionality of this crate (with proc_macros), be sure to check out tablefy_derive!.

Future updates

Currently there are two major improvements I have in mind for this crate.

• Fields can be tagged to customize the header name.
  • This has now been implemented! Be sure to update tablefy_derive.
• Fields can be tagged to print using {:?} and {:#?} instead of {}
