elemIndices :: Word8 -> ByteString -> [Int]
rio RIO.ByteString
O(n) The elemIndices function extends elemIndex, by returning the indices of all elements equal to the query element, in ascending order. This implementation uses memchr(3).
elemIndices :: Word8 -> ByteString -> [Int64]
rio RIO.ByteString.Lazy
O(n) The elemIndices function extends elemIndex, by returning the indices of all elements equal to the query element, in ascending order. This implementation uses memchr(3).
elemIndices :: Eq a => a -> [a] -> [Int]
rio RIO.List
The elemIndices function extends elemIndex, by returning the indices of all elements equal to the query element, in ascending order.

Examples

>>> elemIndices 'o' "Hello World"
[4,7]

>>> elemIndices 1 [1, 2, 3, 1, 2, 3]
[0,3]

elemIndices :: Eq a => a -> Vector a -> Vector Int
rio RIO.Vector.Boxed

elemIndicesL :: Eq a => a -> Seq a -> [Int]
rio RIO.Seq
elemIndicesL finds the indices of the specified element, from left to right (i.e. in ascending order).
elemIndicesR :: Eq a => a -> Seq a -> [Int]
rio RIO.Seq
elemIndicesR finds the indices of the specified element, from right to left (i.e. in descending order).
