elemIndices package:streamly-core

elemIndices :: forall (m :: Type -> Type) a . (Monad m, Eq a) => a -> Fold m a (Maybe Int)
streamly-core Streamly.Data.Fold Streamly.Internal.Data.Fold
Returns the index of the latest element if the element matches the given value. Definition: 
>>> elemIndices a = Fold.findIndices (== a)
elemIndices :: forall (m :: Type -> Type) a . (Monad m, Eq a) => a -> Scanl m a (Maybe Int)
streamly-core Streamly.Data.Scanl Streamly.Internal.Data.Scanl
Returns the index of the latest element if the element matches the given value. Definition: 
>>> elemIndices a = Scanl.findIndices (== a)
elemIndices :: forall (m :: Type -> Type) a . (Monad m, Eq a) => a -> Stream m a -> Stream m Int
streamly-core Streamly.Internal.Data.Stream
Find all the indices where the value of the element in the stream is equal to the given value. 
>>> elemIndices a = Stream.findIndices (== a)
