std::stacktrace_entry

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 >

Member types

native_handle_type

implementation-defined native handle type

Member functions

(constructor)	constructs a new stacktrace_entry (public member function)
(destructor)	destroys the stacktrace_entry (public member function)
operator=	assigns the contents of one stacktrace_entry to another (public member function)
Observers
native_handle	gets the implementation-defined native handle of the stacktrace_entry (public member function)
operator bool	checks whether the stacktrace_entry is empty (public member function)
Query
description	gets the description of the evaluation represented by the stacktrace_entry (public member function)
source_file	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)
source_line	gets the line number that lexically relates the evaluation represented by the stacktrace_entry (public member function)

Non-member functions

operator==operator<=> (C++23)	compares two stacktrace_entry values (function)
to_string (C++23)	returns a string with a description of the stacktrace_entry (function)
operator<< (C++23)	performs stream output of stacktrace_entry (function template)

Helper classes

std::hash<std::stacktrace_entry> (C++23)	hash support for std::stacktrace_entry (class template specialization)
std::formatter<std::stacktrace_entry> (C++23)	formatting support for stacktrace_entry (class template specialization)

Notes

boost::stacktrace::frame (available in Boost.Stacktrace) can be used instead when std::stacktrace_entry
