A collection of macro extensions for Rust's standard library data structures, simplifying the creation and manipulation of common collections such as HashMap, Vec, and more.
/// Creates a new `LinkedList` instance.
////// This macro can be used in two forms:
/// - Without arguments, it creates an empty `LinkedList`.
/// - With elements, it creates a `LinkedList` and appends the provided elements to the back of the list.
