Helper classes

hash<stacktrace_entry> (C++23)

 

constexpr explicit operator bool() const noexcept;		(since C++23)

Checks whether the stacktrace_entry is non-empty, i.e. it represents an evaluation in a stacktrace.

Parameters

(none)

Return value

true if the stacktrace_entry is non-empty, false otherwise.

Notes

A non-empty stacktrace_entry can be obtained from a std::basic_stacktrace created by std::basic_stacktrace::current or a copy of such std::basic_stacktrace.

An empty stacktrace_entry can be created by the default constructor.
