Web Reference: Returns an array of the same size as self, with function f applied to each element in order. If you don’t necessarily need a new fixed-size array, consider using Iterator::map instead. Rust does not have type-level integers, so the size of the array would be necessarily constant in this case. Is it possible to create array with dynamic length? No. By definition, arrays have a length defined at compile time. A variable (because it can vary) is not known at compile time. For operations that require adding and removing array elements, you can use Vectors, which are resizable arrays. The size of a vector is dynamic, meaning it can grow and shrink as needed.
