Module `Array.Smart`

The functions defined in this module are optimized specializations of the main ones, when the returned array is of same type as one of the original array.

val map : ('a -> 'a) -> 'a array -> 'a array: Smart.map f a behaves as map f a but returns a instead of a copy when f x == x for all x in a.

val map_i : (int -> 'a -> 'a) -> 'a array -> 'a array
val map2 : ('a -> 'b -> 'b) -> 'a array -> 'b array -> 'b array: Smart.map2 f a b behaves as map2 f a b but returns a instead of a copy when f x y == y for all x in a and y in b pointwise.

val fold_left_map : ('a -> 'b -> 'a * 'b) -> 'a -> 'b array -> 'a * 'b array: Smart.fold_left_mapf a b behaves as fold_left_map but returns b as second component instead of a copy of b when the output array is pointwise the same as the input array b

val fold_left2_map : ('a -> 'b -> 'c -> 'a * 'c) -> 'a -> 'b array -> 'c array -> 'a * 'c array: Smart.fold_left2_map f a b c behaves as fold_left2_map but returns c as second component instead of a copy of c when the output array is pointwise the same as the input array c
