Method: Bundler::Molinillo::Resolver::Resolution::UnwindDetails#<=>

Defined in:
lib/bundler/vendor/molinillo/lib/molinillo/resolution.rb

#<=>(other) ⇒ Integer

We compare UnwindDetails when choosing which state to unwind to. If two options have the same state_index we prefer the one most removed from a requirement that caused the conflict. Both options would unwind to the same state, but a ‘grandparent` option will filter out fewer of its possibilities after doing so - where a state is both a `parent` and a `grandparent` to requirements that have caused a conflict this is the correct behaviour.

Parameters:

  • other (UnwindDetail) —

    UnwindDetail to be compared

Returns:

  • (Integer) —

    integer specifying ordering
