Description

Destroying it removes the slot from the pool, so keep it alive for as long as the operation runs (typically by capturing it in the operation's completion handler).

`bound_slot` public member functions

```
bound_slot() = default;
```
```
bound_slot(bound_slot &&);
```

bound_slot & operator=(bound_slot && other) noexcept;

bound_slot(bound_slot const &) = delete;

bound_slot & operator=(bound_slot const &) = delete;

```
~bound_slot();
```
```
boost::asio::cancellation_slot slot() const;
```
The cancellation slot to bind to the operation.

void emit(boost::asio::cancellation_type ct = boost::asio::cancellation_type::all) const;

Emit on this slot alone, dispatched through its executor.

```
void release();
```
Remove the slot from the pool now.

`bound_slot` private member functions

bound_slot(std::shared_ptr< state > s, std::shared_ptr< bound_record > r);
