| 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>.

|
implementation-defined native handle type |
Member functions
constructs a new stacktrace_entry (public member function) | |
| (destructor) (C++23) |
destroys the stacktrace_entry (public member function) |
| (C++23) |
assigns the contents of one stacktrace_entry to another (public member function) |
Observers | |
| (C++23) |
gets the implementation-defined native handle of the stacktrace_entry (public member function) |
| (C++23) |
checks whether the stacktrace_entry is empty (public member function) |
Query | |
| (C++23) |
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) | |
gets the line number that lexically relates the evaluation represented by the stacktrace_entry (public member function) | |
Non-member functions
| (C++23) |
compares two stacktrace_entry values (function) |
| (C++23) |
returns a string with a description of the stacktrace_entry (function) |
| (C++23) |
performs stream output of stacktrace_entry (function template) |
Helper classes
| hash support for std::stacktrace_entry (class template specialization) | |
formatting support for stacktrace_entry (class template specialization) |
Notes
boost::stacktrace::frame (available in Boost.Stacktrace) can be used instead when std::stacktrace_entry is not available.
