Macro nccl::vec_into

macro_rules! vec_into {
    ($($item:expr),*) => { ... };
}

Calls .into() on every element added to a new vector.

Examples:

#[derive(Debug, PartialEq)]
struct Empty;
impl Into<Empty> for bool {
    fn into(self) -> Empty {
        Empty
    }
}

impl Into<Empty> for i32 {
    fn into(self) -> Empty {
        Empty
    }
}

impl<'a> Into<Empty> for &'a str {
    fn into(self) -> Empty {
        Empty
    }
}

fn main() {
    let v: Vec<Empty> = vec_into![true, 32, "hello"];
    assert_eq!(v, vec![Empty, Empty, Empty]);
}
