explicit executor_work_guard(const executor_type& ex) noexcept;

1

Effects: Initializes ex_ with ex, and then performs ex_.on_work_started().

2

Postconditions: ex_ == ex and owns_ == true.

executor_work_guard(const executor_work_guard& other) noexcept;

3

Effects: Initializes ex_ with other.ex_. If other.owns_ == true, performs ex_.on_work_started().

4

Postconditions: ex_ == other.ex_ and owns_ == other.owns_.

executor_work_guard(executor_work_guard&& other) noexcept;

5

Effects: Initializes ex_ with std::move(other.ex_) and initializes owns_ with other.owns_, and sets other.owns_ to false.

~executor_work_guard();

6

Effects: If owns_ is true, performs ex_.on_work_finished().

executor_type get_executor() const noexcept;

7

Returns: ex_.

bool owns_work() const noexcept;

8

Returns: owns_.

void reset() noexcept;

9

Effects: If owns_ is true, performs ex_.on_work_finished().

10

Postconditions: owns_ == false.
