< cpp | utility | stacktrace entry

friend constexpr std::strong_ordering operator<=>( const stacktrace_entry& lhs, const stacktrace_entry& rhs ) noexcept; |
(2) | (since C++23) |
1) Compares
lhs
and rhs
for equality. Two stacktrace_entry
values are equal if and only if they represent the same stacktrace entry, or both of them are empty.2) Gets the relative order between
lhs
and rhs
in the unspecified strict total order over all stacktrace_entry
values which is consistent with the equality relation established by operator==
.These functions are not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when std::stacktrace_entry
is an associated class of the arguments.
The <
, <=
, >
, >=
, and !=
operators are synthesized from operator<=> and operator== respectively.
Parameters
lhs, rhs | - | stacktrace_entry values to compare
|
Return value
1) true if two
lhs
and rhs
compare equal, false otherwise.2) std::strong_ordering::equal if
lhs
and rhs
compare equal. Otherwise, std::strong_ordering::less if
lhs
is ordered before rhs
in the strict total order. Otherwise, std::strong_ordering::greater (in which case
rhs
is ordered before lhs
in the strict total order).Example
