Documentation
sourceFile :: MonadResource m => FilePath -> Source m ByteStringSource
Stream the contents of a file as binary data.
Since 0.3.0
sourceHandle :: MonadIO m => Handle -> Source m ByteStringSource
Stream the contents of a Handle as binary data. Note that this
function will not automatically close the Handle when processing
completes, since it did not acquire the Handle in the first place.
Since 0.3.0
sourceIOHandle :: MonadResource m => IO Handle -> Source m ByteStringSource
An alternative to sourceHandle.
Instead of taking a pre-opened Handle, it takes an action that opens
a Handle (in read mode), so that it can open it only when needed
and close it as soon as possible.
Since 0.3.0
Arguments
| :: MonadResource m | |
| => FilePath | |
| -> Maybe Integer | Offset |
| -> Maybe Integer | Maximum count |
| -> Source m ByteString |
Stream the contents of a file as binary data, starting from a certain offset and only consuming up to a certain number of bytes.
Since 0.3.0
sinkFile :: MonadResource m => FilePath -> Sink ByteString m ()Source
Stream all incoming data to the given file.
Since 0.3.0
sinkHandle :: MonadIO m => Handle -> Sink ByteString m ()Source
Stream all incoming data to the given Handle. Note that this function
will not automatically close the Handle when processing completes.
Since 0.3.0
sinkIOHandle :: MonadResource m => IO Handle -> Sink ByteString m ()Source
An alternative to sinkHandle.
Instead of taking a pre-opened Handle, it takes an action that opens
a Handle (in write mode), so that it can open it only when needed
and close it as soon as possible.
Since 0.3.0
conduitFile :: MonadResource m => FilePath -> Conduit ByteString m ByteStringSource
Stream the contents of the input to a file, and also send it along the
pipeline. Similar in concept to the Unix command tee.
Since 0.3.0
isolate :: Monad m => Int -> Conduit ByteString m ByteStringSource
Ensure that only up to the given number of bytes are consume by the inner sink. Note that this does not ensure that all of those bytes are in fact consumed.
Since 0.3.0
openFile :: MonadResource m => FilePath -> IOMode -> m HandleSource
Open a file Handle safely by automatically registering a release
action.
While you are not required to call hClose on the resulting handle, you
should do so as early as possible to free scarce resources.
Since 0.3.0
head :: Monad m => Sink ByteString m (Maybe Word8)Source
Return the next byte from the stream, if available.
Since 0.3.0
takeWhile :: Monad m => (Word8 -> Bool) -> Conduit ByteString m ByteStringSource
Return all bytes while the predicate returns True.
Since 0.3.0
dropWhile :: Monad m => (Word8 -> Bool) -> Sink ByteString m ()Source
Ignore all bytes while the predicate returns True.
Since 0.3.0
take :: Monad m => Int -> Sink ByteString m ByteStringSource
Take the given number of bytes, if available.
Since 0.3.0
lines :: Monad m => Conduit ByteString m ByteStringSource
Split the input bytes into lines. In other words, split on the LF byte (10), and strip it from the output.
Since 0.3.0
