Function cl_traits::try_create_array

pub fn try_create_array<E, F, T, const N: usize>(cb: F) -> Result<[T; N], E> where
    F: FnMut(usize) -> Result<T, E>, 

Creates a fallible array [T; N] where each array element T is returned by the cb call.

• Example

use cl_traits::try_create_array;

#[derive(Debug, PartialEq)]
enum SomeError {
  Foo
}

let array: Result<[usize; 5], SomeError> = try_create_array(|i| Ok(i));
assert_eq!(array, Ok([0, 1, 2, 3, 4]));

let another_array: Result<[usize; 5], SomeError> = try_create_array(|_| Err(SomeError::Foo));
assert_eq!(another_array, Err(SomeError::Foo));
