basic_result(const failure_type<T> &)
Implicit error-from-failure-type-sugar copy constructor used to disambiguate the construction of the error type.
Note that if T = void
, error_type
will be default constructed. Calls void on_result_copy_construction(T *, U &&) noexcept
with this
and const failure_type<T> &
.
Requires: predicate::enable_make_exception_ptr_compatible_conversion<void, T, void>
is true, or T
is void
.
Complexity: Same as for the error_type
constructor which accepts T
, or the error_type
default constructor if T
is void
. Constexpr, triviality and noexcept of underlying operations is propagated.
