head :: Monad m => Iteratee a m (Maybe a)

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 ()

drop n ignores n input elements from the stream.

Since: 0.4.5

dropWhile :: Monad m => (a -> Bool) -> Iteratee a m ()

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]

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]

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]

Read all remaining input elements from the stream, and return as a list.

Since: 0.4.5

require :: Monad m => Integer -> Iteratee a m ()

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 b

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.
