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>
.
native_handle_type (C++23) | implementation-defined native handle type |
(C++23) | 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) |
(C++23) | 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) |
(C++23) | gets the line number that lexically relates the evaluation represented by the stacktrace_entry (public member function) |
(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) |
(C++23) | hash support for std::stacktrace_entry (class template specialization) |
(C++23) | formatting support for stacktrace_entry (class template specialization) |
boost::stacktrace::frame
(available in Boost.Stacktrace) can be used instead when std::stacktrace_entry
is not available.

__cpp_lib_stacktrace | 202011L | (C++23) | Stacktrace library |
(C++23) | approximate representation of an invocation sequence consists of stacktrace entries (class template) |
(C++20) | a class representing information about the source code, such as file names, line numbers, and function names (class) |
