valuerunParser

:: (MonadIO m, MonadBaseControl IO m)
=> NarEffects m
Provide the effects set, usually narEffectsIO
-> NarParser m a
A parser to run, such as parseNar
-> Handle
A handle the stream containg the NAR. It should already be open and in ReadMode
-> FilePath
The root file system object to be created by the NAR
-> m (Either String a)

Run a NarParser over a byte stream This is suitable for testing the top-level NAR parser, or any of the smaller utilities parsers, if you have bytes appropriate for them

valuerunParserWithOptions

:: (MonadIO m, MonadBaseControl IO m)
=> NarOptions
-> NarEffects m
Provide the effects set, usually narEffectsIO
-> NarParser m a
A parser to run, such as parseNar
-> Handle
A handle the stream containg the NAR. It should already be open and in ReadMode
-> FilePath
The root file system object to be created by the NAR
-> m (Either String a)

valueparseNar :: (MonadIO m, MonadFail m) => NarParser m ()

Parse a NAR byte string, producing (). Parsing a NAR is mostly used for its side-effect: producing the file system objects packed in the NAR. That's why we pure ()

valuetestParser :: m ~ IO => NarParser m a -> ByteString -> m (Either String a)
