Eq Action

Defined in System.Nix.GC

Methods

(==) :: Action -> Action -> Bool

(/=) :: Action -> Action -> Bool

Ord Action

Defined in System.Nix.GC

Methods

compare :: Action -> Action -> Ordering

(<) :: Action -> Action -> Bool

(<=) :: Action -> Action -> Bool

(>) :: Action -> Action -> Bool

(>=) :: Action -> Action -> Bool

data Options

Garbage collector operation options

Constructors

Options

Fields

• operation :: !Action

  operation

• ignoreLiveness :: !Bool

  If ignoreLiveness is set, then reachability from the roots is ignored (dangerous!). However, the paths must still be unreferenced *within* the store (i.e., there can be no other store paths that depend on them).

• pathsToDelete :: !PathSet

  For DeleteSpecific, the paths to delete

• maxFreed :: !Integer

  Stop after at least maxFreed bytes have been freed

Constructors

Result

Fields

• paths :: !PathSet
