Macro vecmin 

macro_rules! vecmin {
    ($min:expr; [$x:expr; $n:expr]) => { ... };
    ($min:expr; [$($x:expr),+ $(,)?]) => { ... };

}

Creates a VecMin containing the arguments.

There is a minimum length argument preceding the list, if not included the minimum is inferred as the length. The length must be constant, for non-constant length use checked constructors.

• Create a VecMin with a fixed minimum length:

use vecmin::vecmin;

let v = vecmin![5; [1; 6]];
assert!(!v.is_minimum());
assert_eq!(v.minimum(), 5);

let v = vecmin![2; [1, 2, 3]];
assert!(!v.is_minimum());
assert_eq!(v.minimum(), 2);

• Create a VecMin with a minimum length inferred from the number of elements:

use vecmin::vecmin;

let v = vecmin![1; 6];
assert!(v.is_minimum());
assert_eq!(v.minimum(), 6);

let v = vecmin![1, 2, 3];
assert!(v.is_minimum());
assert_eq!(v.minimum(), 3);
