A move accept token is a completion
token for completion signature void(error_code, typename Protocol::socket)
or completion signature void(error_code, typename Protocol::socket::template rebind_executor<Executor>::other)
, for the type Protocol
of the acceptor class template.
A free function as a move accept token:
void accept_handler( const asio::error_code& ec, asio::ip::tcp::socket s) { ... }
A move accept token function object:
struct accept_handler { ... void operator()( const asio::error_code& ec, asio::ip::tcp::socket s) { ... } ... };
A lambda as a move accept token:
acceptor.async_accept(..., [](const asio::error_code& ec, asio::ip::tcp::socket s) { ... });
A non-static class member function adapted to a move accept token using
std::bind()
:
void my_class::accept_handler( const asio::error_code& ec, asio::ip::tcp::socket socket) { ... } ... asio::async_accept(..., std::bind(&my_class::accept_handler, this, std::placeholders::_1, std::placeholders::_2));
Using use_future as a move accept token:
std::future<asio::ip::tcp::socket> f = acceptor.async_accept(..., asio::use_future); ... try { asio::ip::tcp::socket s = f.get(); ... } catch (const system_error& e) { ... }
Using use_awaitable as a move accept token:
asio::awaitable<void> my_coroutine() { try { ... asio::ip::tcp::socket s = co_await acceptor.async_accept( ..., asio::use_awaitable); ... } catch (const system_error& e) { ... } }
