Description

Folds for byte streams

Synopsis

Folding

fold :: Fold ByteString a -> ByteString -> a Source #

Apply a strict left Fold to a lazy bytestring

foldM :: Monad m => FoldM m ByteString a -> ByteString -> m a Source #

Apply a strict monadic left FoldM to a lazy bytestring

Folds

head :: Fold ByteString (Maybe Word8) Source #

Get the first byte of a byte stream or return Nothing if the stream is empty

last :: Fold ByteString (Maybe Word8) Source #

Get the last byte of a byte stream or return Nothing if the byte stream is empty

null :: Fold ByteString Bool Source #

Returns True if the byte stream is empty, False otherwise

length :: Num n => Fold ByteString n Source #

Return the length of the byte stream in bytes

any :: (Word8 -> Bool) -> Fold ByteString Bool Source #

(any predicate) returns True if any byte satisfies the predicate, False otherwise

all :: (Word8 -> Bool) -> Fold ByteString Bool Source #

(all predicate) returns True if all bytes satisfy the predicate, False otherwise

maximum :: Fold ByteString (Maybe Word8) Source #

Computes the maximum byte

minimum :: Fold ByteString (Maybe Word8) Source #

Computes the minimum byte

elem :: Word8 -> Fold ByteString Bool Source #

(elem w8) returns True if the byte stream has a byte equal to w8, False otherwise

notElem :: Word8 -> Fold ByteString Bool Source #

(notElem w8) returns False if the byte stream has a byte equal to w8, True otherwise

find :: (Word8 -> Bool) -> Fold ByteString (Maybe Word8) Source #

(find predicate) returns the first byte that satisfies the predicate or Nothing if no byte satisfies the predicate

index :: Integral n => n -> Fold ByteString (Maybe Word8) Source #

(index n) returns the nth byte of the byte stream, or Nothing if the stream has an insufficient number of bytes

elemIndex :: Num n => Word8 -> Fold ByteString (Maybe n) Source #

(elemIndex w8) returns the index of the first byte that equals w8, or Nothing if no byte matches

findIndex :: Num n => (Word8 -> Bool) -> Fold ByteString (Maybe n) Source #

(findIndex predicate) returns the index of the first byte that satisfies the predicate, or Nothing if no byte satisfies the predicate

count :: Num n => Word8 -> Fold ByteString n Source #

count w8 returns the number of times w8 appears

lazy :: Fold ByteString ByteString Source #

Combine all the strict ByteString chunks to build a lazy ByteString

Re-exports

Control.Foldl re-exports the Fold type

Data.ByteString re-exports the ByteString type

Data.Word re-exports the Word8 type

class Foldable (t :: Type -> Type) #

Data structures that can be folded.

For example, given a data type

data Tree a = Empty | Leaf a | Node (Tree a) a (Tree a)

a suitable instance would be

instance Foldable Tree where
   foldMap f Empty = mempty
   foldMap f (Leaf x) = f x
   foldMap f (Node l k r) = foldMap f l `mappend` f k `mappend` foldMap f r

This is suitable even for abstract types, as the monoid is assumed to satisfy the monoid laws. Alternatively, one could define foldr:

instance Foldable Tree where
   foldr f z Empty = z
   foldr f z (Leaf x) = f x z
   foldr f z (Node l k r) = foldr f (f k (foldr f z r)) l

Foldable instances are expected to satisfy the following laws:

foldr f z t = appEndo (foldMap (Endo . f) t ) z
foldl f z t = appEndo (getDual (foldMap (Dual . Endo . flip f) t)) z
fold = foldMap id
length = getSum . foldMap (Sum . const  1)

sum, product, maximum, and minimum should all be essentially equivalent to foldMap forms, such as

sum = getSum . foldMap Sum

but may be less defined.

If the type is also a Functor instance, it should satisfy

foldMap f = fold . fmap f

which implies that

foldMap f . fmap g = foldMap (f . g)
