Detailed Description

Provides a registry of PkgDb managers.

Derived classes must provide their own getRegistryRaw and getSystems implementations to support initRegistry and scrapeIfNeeded.

Member Function Documentation

nix::ref< Registry< PkgDbInputFactory > > flox::pkgdb::PkgDbRegistryMixin::getPkgDbRegistry ( )

Lazily perform scraping on input flakes.

If scraping is necessary temprorary read/write handles are opened for those flakes and closed before returning from this function.
