Stops any current outstanding operation and marks the pool as cancelled.
void cancel();
This function has the following effects:
async_run operation, if any,
which will complete with a success error code.
async_get_connection operations,
which will complete with client_errc::cancelled.
async_get_connection
calls will complete immediately with client_errc::cancelled.
This function will return immediately, without waiting for the cancelled operations to complete.
You may call this function any number of times. Successive calls will have no effect.
this->valid() == true
Basic guarantee. Memory allocations and acquiring mutexes may throw.
When the pool is constructed with adequate executor configuration, this
function is safe to be called concurrently with async_run, async_get_connection, ~pooled_connection
and pooled_connection::return_without_reset.
