elemIndex :: (Vector v a, Eq a) => a -> Vector v n a -> Maybe (Finite n)
vector-sized Data.Vector.Generic.Sized
O(n) Yield Just the index of the first occurence of the given element or Nothing if the vector does not contain the element. This is a specialised version of findIndex.
elemIndex :: (Prim a, Eq a) => a -> Vector n a -> Maybe (Finite n)
vector-sized Data.Vector.Primitive.Sized
O(n) Yield Just the index of the first occurence of the given element or Nothing if the vector does not contain the element. This is a specialised version of findIndex.
elemIndex :: Eq a => a -> Vector n a -> Maybe (Finite n)
vector-sized Data.Vector.Sized
O(n) Yield Just the index of the first occurence of the given element or Nothing if the vector does not contain the element. This is a specialised version of findIndex.
elemIndex :: (Storable a, Eq a) => a -> Vector n a -> Maybe (Finite n)
vector-sized Data.Vector.Storable.Sized
O(n) Yield Just the index of the first occurence of the given element or Nothing if the vector does not contain the element. This is a specialised version of findIndex.
elemIndex :: (Unbox a, Eq a) => a -> Vector n a -> Maybe (Finite n)
vector-sized Data.Vector.Unboxed.Sized
O(n) Yield Just the index of the first occurence of the given element or Nothing if the vector does not contain the element. This is a specialised version of findIndex.
