Defined in header <stacktrace>
class stacktrace_entry;
(since C++23)

The stacktrace_entry class provides operations for querying information about an evaluation in a stacktrace. Each stacktrace_entry object is either empty, or represents an evaluation in a stacktrace.

stacktrace_entry models std::regular and std::three_way_comparable<std::strong_ordering>.
