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>.

[edit] Member functions

constructs a new stacktrace_entry
(public member function) [edit]
destroys the stacktrace_entry
(public member function)
assigns the contents of one stacktrace_entry to another
(public member function)
gets the implementation-defined native handle of the stacktrace_entry
(public member function)
checks whether the stacktrace_entry is empty
(public member function)
gets the description of the evaluation represented by the stacktrace_entry
(public member function)
gets the name of the source file that lexically contains the expression or statement whose evaluation is represented by the stacktrace_entry
(public member function) [edit]
gets the line number that lexically relates the evaluation represented by the stacktrace_entry
(public member function) [edit]

[edit] Non-member functions

compares two stacktrace_entry values
returns a string with a description of the stacktrace_entry
(function) [edit]
performs stream output of stacktrace_entry

[edit] Helper classes

hash support for std::stacktrace_entry
(class template specialization) [edit]
formatting support for stacktrace_entry

[edit] Notes

boost::stacktrace::frame (available in Boost.Stacktrace) can be used instead when std::stacktrace_entry is not available.
