Method: Bundler::PubGrub::VersionRange#span

Defined in:
lib/bundler/vendor/pub_grub/lib/pub_grub/version_range.rb

#span(other) ⇒ Object

The span covered by two ranges

If self and other are contiguous, this builds a union of the two ranges. (if they aren’t you are probably calling the wrong method)
