Bio.Iteratee.IO.Fd
Description
Random and Binary IO with generic Iteratees, using File Descriptors for IO. when available, these are the preferred functions for performing IO as they run in constant space and function properly with sockets, pipes, etc.
- enumFd :: forall s el m a. (NullPoint s, ReadableChunk s el, MonadIO m, MonadMask m) => Int -> Fd -> Enumerator s m a
- enumFdCatch :: forall e s el m a. (IException e, NullPoint s, ReadableChunk s el, MonadIO m, MonadMask m) => Int -> Fd -> (e -> m (Maybe EnumException)) -> Enumerator s m a
- enumFdRandom :: forall s el m a. (NullPoint s, ReadableChunk s el, MonadIO m, MonadMask m) => Int -> Fd -> Enumerator s m a
- enumFile :: (NullPoint s, MonadIO m, MonadMask m, ReadableChunk s el) => Int -> FilePath -> Enumerator s m a
- enumFileRandom :: (NullPoint s, MonadIO m, MonadMask m, ReadableChunk s el) => Int -> FilePath -> Enumerator s m a
- fileDriverFd :: (NullPoint s, MonadIO m, MonadMask m, ReadableChunk s el) => Int -> Iteratee s m a -> FilePath -> m a
- fileDriverRandomFd :: (NullPoint s, MonadIO m, MonadMask m, ReadableChunk s el) => Int -> Iteratee s m a -> FilePath -> m a
File enumerators
FileDescriptor based enumerators for monadic iteratees
enumFd :: forall s el m a. (NullPoint s, ReadableChunk s el, MonadIO m, MonadMask m) => Int -> Fd -> Enumerator s m a Source #
The enumerator of a POSIX File Descriptor. This version enumerates over the entire contents of a file, in order, unless stopped by the iteratee. In particular, seeking is not supported.
enumFdCatch :: forall e s el m a. (IException e, NullPoint s, ReadableChunk s el, MonadIO m, MonadMask m) => Int -> Fd -> (e -> m (Maybe EnumException)) -> Enumerator s m a Source #
A variant of enumFd that catches exceptions raised by the Iteratee.
enumFdRandom :: forall s el m a. (NullPoint s, ReadableChunk s el, MonadIO m, MonadMask m) => Int -> Fd -> Enumerator s m a Source #
The enumerator of a POSIX File Descriptor: a variation of enumFd that
supports RandomIO (seek requests).
