explicit basic_result(ValueOrError<T, E> &&)
Explicit converting constructor from
concept matching types. Delegates to the
basic_result move constructor.
has an available call operator, and if the input is a
convert::value_or_error<> has enabled those inputs for that
Complexity: Same as for the copy or move constructor from the input’s
.error() respectively. Constexpr, triviality and noexcept of underlying operations is propagated.
Guarantees: If an exception is thrown during the operation, the object is left in a partially completed state, as per the normal rules for the same operation on a
