# `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_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.
