Distribution.Solver.Types.SolverId

Synopsis

- data SolverId
  - = PreExistingId {
    - solverSrcId :: PackageId
    - solverInstId :: UnitId
    }
  - | PlannedId {
    - solverSrcId :: PackageId
    }

# Documentation

data SolverId #

The solver can produce references to existing packages or packages we plan to install. Unlike `ConfiguredId` we don't yet know the `UnitId` for planned packages, because it's not the solver's job to compute them.

Constructors

Fields solverSrcId :: PackageId solverInstId :: UnitId
