History
bool operator==(const basic_result<A, B, C> &) const
Returns true if this result compares equal to the other result. Comparison is done using operator==
on either value_type
or error_type
if the currently chosen state is the same for both results, otherwise false is returned.
Requires : operator==
must be a valid expression between value_type
and A
, and between error_type
and B
. If value_type
is void
, then so must be A
; similarly for error_type
and B
.
Complexity : Whatever the underlying operator==
have. Constexpr and noexcept of underlying operations is propagated.
Guarantees : None.
Free function alias : There is a free function bool operator==(const basic_result<A, B, C> &, const basic_outcome<A, B, C, D> &)
which forwards perfectly to this function, by reversing the operands.
