Garbage collector operation options

Constructors

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

Instances

Eq Options Source #

Ord Options Source #

Constructors

Result
Fields paths :: !PathSet Depending on the action, the GC roots, or the paths that would be or have been deleted bytesFreed :: !Integer For ReturnDead, DeleteDead and DeleteSpecific, the number of bytes that would be or was freed
