valuestream :: Text -> Stream Char

Source#

O(n) Convert a Text into a 'Stream Char'.

valuestreamLn :: Text -> Stream Char

Source#

O(n) streamLn t = stream (t <> '\n')

valueunstream :: Stream Char -> Text

Source#

O(n) Convert a 'Stream Char' into a Text, using defaultChunkSize.

valueunstreamChunks :: Int -> Stream Char -> Text

Source#

O(n) Convert a 'Stream Char' into a Text, using the given chunk size.

valuelength :: Stream Char -> Int64

Source#

O(n) Returns the number of characters in a text.

valueunfoldrN :: Int64 -> (a -> Maybe (Char, a)) -> a -> Stream Char

Source#

O(n) Like unfoldr, unfoldrN builds a stream from a seed value. However, the length of the result is limited by the first argument to unfoldrN. This function is more efficient than unfoldr when the length of the result is known.

valueindex :: HasCallStack => Stream Char -> Int64 -> Char

Source#

O(n) stream index (subscript) operator, starting from 0.

valuecountChar :: Char -> Stream Char -> Int64

Source#

O(n) The count function returns the number of times the query element appears in the given stream.
