You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: collections.rs
    path of file: ./repos/sugars/src
    
    the code of the file until where you have to start completion: //! Module for collections literal macros.

#[doc(hidden)]
#[macro_export]
macro_rules! count {
    (@subst $($x: tt)*) => (());
    ($($rest: expr),*) => (<[()]>::len(&[$($crate::count!(@subst $rest)),*]));
}

/// Create a [`HashMap`] from a list of key-value pairs.
///
/// # Example
///
/// ```rust
/// use sugars::hmap;
///
/// # fn main() {
/// let map = hmap
    
    fn bheap() {
        let bheap1: BinaryHeap<()> = bheap![];
        assert!(bheap1.is_empty());

        let bheap2 = bheap![1, 2, 3, 4, 5,];
        let bheap2_test = {
            let mut bh = BinaryHeap::new();
            bh.push(1);
            bh.push(2);
            bh.push(3);
            bh.push(4);
            bh.push(5);
            bh
        };

        for (test, bh_i) in bheap2_test.iter().zip(bheap2.iter()) {
            assert_eq!(test, bh_i);
        }
    }
