head :: Monad m => Iteratee a m (Maybe a)Source
Get the next element from the stream, or Nothing
if the stream has
ended.
Since: 0.4.5
drop :: Monad m => Integer -> Iteratee a m ()Source
drop n
ignores n input elements from the stream.
Since: 0.4.5
dropWhile :: Monad m => (a -> Bool) -> Iteratee a m ()Source
dropWhile p
ignores input from the stream until the first element
which does not match the predicate.
Since: 0.4.5
take :: Monad m => Integer -> Iteratee a m [a]Source
take n
extracts the next n elements from the stream, as a list.
Since: 0.4.5
takeWhile :: Monad m => (a -> Bool) -> Iteratee a m [a]Source
takeWhile p
extracts input from the stream until the first element
which does not match the predicate.
Since: 0.4.5
consume :: Monad m => Iteratee a m [a]Source
Read all remaining input elements from the stream, and return as a list.
Since: 0.4.5
require :: Monad m => Integer -> Iteratee a m ()Source
require n
buffers input until at least n elements are available, or
throws an error if the stream ends early.
Since: 0.4.5
isolate :: Monad m => Integer -> Enumeratee a a m bSource
isolate n
reads at most n elements from the stream, and passes them
to its iteratee. If the iteratee finishes early, elements continue to be
consumed from the outer stream until n have been consumed.
