basic_result(ErrorCondEnum &&) - Boost.Outcome documentation

# `basic_result(ErrorCondEnum &&)`

Implicit `error_type` from `ErrorCondEnum` constructor. Calls `void hook_result_construction(T *, U &&) noexcept` with `this` and `ErrorCondEnum`.

Requires: `predicate::enable_error_condition_converting_constructor<R>` is true.

Complexity: Same as for `error_type`’s copy or move constructor from the result of `make_error_code(ErrorCondEnum)`. Constexpr, triviality and noexcept of underlying operations is propagated.

Guarantees: If an exception is thrown during the operation, the state of the input is left indeterminate.
