typetype NarSource (m :: Type -> Type) = (ByteString -> m ()) -> m ()

NarSource The source to provide nar to the handler `(ByteString -> m ())`. It is isomorphic to ByteString by Yoneda lemma if the result is meant to be m (). It is done in CPS style so IO can be chunks.

valuedumpString

:: MonadIO m
=> ByteString
the string you want to dump
-> NarSource m
The nar result in CPS style

dumpString dump a string to nar in CPS style. The function takes in a ByteString, and build a `NarSource m`.

valuedumpPath

:: MonadIO m
=> FilePath
path for the file you want to dump to nar
-> NarSource m
the nar result in CPS style

dumpPath shorthand build a Source that turn file path to nar using the default narEffectsIO.

valuestreamNarIO :: MonadIO m => NarEffects IO -> FilePath -> NarSource m

This implementation of Nar encoding takes an arbitrary yield function from any streaming library, and repeatedly calls it while traversing the filesystem object to Nar encode
