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).
