/// A marker type which is used in arguments list to indicate that there are
/// some other arguments that are omitted.

/// It is formatted as a `...` placeholder.

/// This type is not intended to be used directly. Consider using macros like
/// [`build_unwind_context_data`] or [`unwind_context`] instead.

/// # Examples
///
/// ```rust
/// let arg = unwind_context::UnwindContextArg::new(None, unwind_context::NonExhaustiveMarker);
/// ```
///
/// [`build_unwind_context_data`]: crate::build_unwind_context_data
