示例

use vecmerge::vecmerge;

assert_eq! {
    vecmerge!([1, 2, 3] + [4, 5] + [6]),
    vec![1, 2, 3, 4, 5, 6],
}

let a = vec![1, 2, 3];
let b = vec![6];

assert_eq! {
    vecmerge!(a + [4, 5] + b),
    vec![1, 2, 3, 4, 5, 6],
}

assert_eq! {
    vecmerge!(vec![1, 2, 3] + vec![4, 5, 6]),
    vec![1, 2, 3, 4, 5, 6],
}

assert_eq! {
    vecmerge!([Some(1)]? + [None]? + [Some(3)]? + [4, 5, 6]),
    vec![1, 3, 4, 5, 6],
}

assert_eq! {
    vecmerge!([Some(1), Some(2), Some(3)]? + [4, 5, 6]),
    vec![1, 2, 3, 4, 5, 6],
}

assert_eq! {
    vecmerge!([Some(1), None, Some(3)]? + [4, 5, 6]),
    vec![4, 5, 6],
}
