streamly Streamly.Internal.Data.Stream.IsStream enumerateTo = enumerateFromTo minBound
Enumerate a Bounded type from its minBound to specified value. -
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]

This codec is similar to read but provides much better error messages than read for nullary sum types. E.g. for the same Format example from read function, but with the Toml.enumBounded "foo" codec the error for foo = "Jif" in the TOML file will look like this:
tomland decode error: Value is Jif but expected one of: Jpeg, Png, Gif
