1/// Handy macro to construct a hashmap
2///
3/// Example:
4///
5/// ```rust
6/// # use bubble_bath::hashmap;
7/// # use std::collections::HashMap;
8/// let _: HashMap<_, HashMap<_, _>> = hashmap! [
9///     "key" => hashmap![],
10///     "key2" => hashmap![
11///         "inner key" => "inner value",
12///     ],
13/// ];
14/// ```

16macro_rules! hashmap {
17    ($($key:expr => $value:expr),*$(,)?) => {{
18        let mut hashmap = ::std::collections::HashMap::default();

22        )*

28/// Handy macro to construct a hashset
29///
30/// Example:

34/// # use std::collections::HashSet;
35/// let _ : HashSet<_> = hashset![
36///     "key1",
37///     "key2",
