3/// A marker type which is used in arguments list to indicate that there are
4/// some other arguments that are omitted.
5///
6/// It is formatted as a `...` placeholder.
7///
8/// This type is not intended to be used directly. Consider using macros like
9/// [`build_unwind_context_data`] or [`unwind_context`] instead.
10///
11/// # Examples
12///
13/// ```rust
14/// let arg = unwind_context::UnwindContextArg::new(None, unwind_context::NonExhaustiveMarker);
15/// ```

17/// [`build_unwind_context_data`]: crate::build_unwind_context_data
