# Macro indexmap::indexset [−] [src]

    macro_rules! indexset {
        (@single $($x:tt)*) => { ... };
        (@count $($rest:expr),*) => { ... };
        ($($value:expr,)+) => { ... };

Create an `IndexSet` from a list of values

## Example

    use indexmap::indexset;

    let set = indexset!{
        "a",
        "b",
    };
    assert!(set.contains("a"));
    assert!(set.contains("b"));
    assert!(!set.contains("c"));

    // "a" is the first value
    assert_eq!(set.iter().next(), Some(&"a"));
