class Bundler::Resolver::Candidate
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.
