streamly Streamly.Internal.Data.Stream.IsStream enumerateTo = enumerateFromTo minBound
Enumerate a Bounded type from its minBound to specified value. -
streamly Streamly.Prelude Types that can be enumerated as a stream. The operations in this type class are equivalent to those in the Enum type class, except that these generate a stream instead of a list. Use the functions in Streamly.Internal.Data.Stream.Enumeration module to define new instances.

streamly Streamly.Prelude enumerate = enumerateFrom minBound
Enumerate a Bounded type from its minBound to maxBound enumerateFrom :: forall t (m :: Type -> Type) . (Enumerable a, IsStream t, Monad m) => a -> t m astreamly Streamly.Prelude enumerateFrom from generates a stream starting with the element from, enumerating up to maxBound when the type is Bounded or generating an infinite stream when the type is not Bounded.
>>> Stream.toList $ Stream.take 4 $ Stream.enumerateFrom (0 :: Int) [0,1,2,3]
For Fractional types, enumeration is numerically stable. However, no overflow or underflow checks are performed.>>> Stream.toList $ Stream.take 4 $ Stream.enumerateFrom 1.1 [1.1,2.1,3.1,4.1]
-
streamly Streamly.Prelude enumerateFromThen from then generates a stream whose first element is from, the second element is then and the successive elements are in increments of then - from. Enumeration can occur downwards or upwards depending on whether then comes before or after from. For Bounded types the stream ends when maxBound is reached, for unbounded types it keeps enumerating infinitely.
>>> Stream.toList $ Stream.take 4 $ Stream.enumerateFromThen 0 2 [0,2,4,6] >>> Stream.toList $ Stream.take 4 $ Stream.enumerateFromThen 0 (-2) [0,-2,-4,-6]
-
streamly Streamly.Prelude enumerateFromThenTo from then to generates a finite stream whose first element is from, the second element is then and the successive elements are in increments of then - from up to to. Enumeration can occur downwards or upwards depending on whether then comes before or after from.
>>> Stream.toList $ Stream.enumerateFromThenTo 0 2 6 [0,2,4,6] >>> Stream.toList $ Stream.enumerateFromThenTo 0 (-2) (-6) [0,-2,-4,-6]
-
streamly Streamly.Prelude Generate a finite stream starting with the element from, enumerating the type up to the value to. If to is smaller than from then an empty stream is returned.
>>> Stream.toList $ Stream.enumerateFromTo 0 4 [0,1,2,3,4]
For Fractional types, the last element is equal to the specified to value after rounding to the nearest integral value.>>> Stream.toList $ Stream.enumerateFromTo 1.1 4 [1.1,2.1,3.1,4.1] >>> Stream.toList $ Stream.enumerateFromTo 1.1 4.6 [1.1,2.1,3.1,4.1,5.1]
