Types

class ListLike (c el) el => StreamChunk c el where Source

Class of types that can be used to hold chunks of data within Iteratee streams. Methods length :: c el -> Int Source Length of currently available data. null :: c el -> Bool Source Test if the current stream is null. cons :: el -> c el -> c el Source Prepend an element to the front of the data. head :: c el -> el Source Return the first element of the stream. tail :: c el -> c el Source Return the tail of the stream. findIndex :: (el -> Bool) -> c el -> Maybe Int Source First index matching the predicate. splitAt :: Int -> c el -> (c el, c el) Source Split the data at the specified index. dropWhile :: (el -> Bool) -> c el -> c el Source Drop data matching the predicate. fromList :: [el] -> c el Source Create a stream from a list. toList :: c el -> [el] Source Create a list from the stream. cMap :: StreamChunk c' el' => (el -> el') -> c el -> c' el' Source Map a computation over the stream. Instances StreamChunk [] el StreamChunk WrappedByteString Char StreamChunk WrappedByteString Word8

class StreamChunk s el => ReadableChunk s el where Source

Class of streams which can be filled from a Ptr. Typically these are streams which can be read from a file. Methods readFromPtr :: Ptr el -> Int -> IO (s el) Source Instances Storable el => ReadableChunk [] el ReadableChunk WrappedByteString Char ReadableChunk WrappedByteString Word8
