Module bpaf::batteries

Batteries included - helpful parsers that use only public API

bpaf comes with a few extra functions that use only public API in their implementation. You might find them useful either for your code or as an inspiration source

To use anything in this module you need to enable batteries cargo feature.

Examples contain combinatoric usage, for derive usage you should create a parser function and use external annotation.

• toggle_flag
  Pick last passed value between two different flags
