module Bundler
class Resolver
#
# This class is a PubGrub compatible "Version" class that takes Bundler
# resolution complexities into account.
#
# Each Resolver::Candidate has a underlying `Gem::Version` plus a set of
# platforms. For example, 1.1.0-x86_64-linux is a different resolution candidate
# from 1.1.0 (generic). This is because different platform variants of the
# same gem version can bring different dependencies, so they need to be
# considered separately.
#
# Some candidates may also keep some information explicitly about the
# package they refer to. These candidates are referred to as "canonical" and
# are used when materializing resolution results back into RubyGems
# specifications that can be installed, written to lock files, and so on.
