Typedef Documentation

ResolutionFailure

using flox::resolver::ResolutionFailure = typedef std::vector<std::pair<InstallID, std::string> >

A pair of install ID and locked flake URLs used to record failed resolution attempts for a given descriptor.

This allows us to more easily format exception messages.

ResolutionResult

using flox::resolver::ResolutionResult = typedef std::variant<ResolutionFailure, SystemPackages>

Either a set of resolved packages ( for a given system ) or a memo indicating that resolution failed for certain descriptors against certain inputs.

When attempting to resolve a group of packages for a given system, we either succeed and return flox::resolver::SystemPackages or fail and return flox::resolver::ResolutionFailure. This allows us to print descriptors that failed as groups for a given input+rev.
