Class to represent an error code value.

The system_error class is used to represent system conditions that prevent the library from operating correctly.

A simple abstraction for starting threads. * The asio::thread class implements the smallest possible subset of the * functionality of boost::thread.

Exception thrown when there are multiple pending exceptions to rethrow.

A cancellation state is used for chaining signals and slots in compositions.

Awaitable to get the current executor. For example: ``` auto current_executor = co_await CurrentExecutor{}; ```

Implements IP version 4 style addresses. * The asio::ip::address_v4 class provides the ability to use and * manipulate IP version 4 addresses. * *

A property to describe whether task submission is likely in the future.

Type used to identify a registered buffer.

A Uthread is a stackful coroutine which would checkin/checkout based on context switching. A user shouldn't use Uthread directly. He should use async/

Helper class for implementating an IP endpoint.

A special type, similar to std::nothrow_t, used to disambiguate constructors that accept executor arguments. * The executor_arg_t struct is an empty s

A property to describe what guarantees an executor makes about the blocking behaviour of their execution functions.

Wait until an operation completes with an error, then cancel the others. * If no operation completes with an error, waits for completion of all * ope

Wait until an operation completes without an error, then cancel the others. * If no operation completes without an error, waits for completion of all

A property to describe whether submitted tasks represent continuations of the calling context.

Unit plays the role of a simplest type in case we couldn't use void directly. User shouldn't use this directly.

Implements IP version 6 style addresses. * The asio::ip::address_v6 class provides the ability to use and * manipulate IP version 6 addresses. * *

Represents an IPv4 network. * The asio::ip::network_v4 class provides the ability to use and * manipulate IP version 4 networks. * * @par Thread Sa

Class to adapt a detached_t as a completion handler.

Class used to specify that an asynchronous operation is detached. * The detached_t class is used to indicate that an asynchronous operation is * deta

Holds a registered buffer over modifiable data. * Satisfies the @c MutableBufferSequence type requirements. */

Represents an IPv6 network. * The asio::ip::network_v6 class provides the ability to use and * manipulate IP version 6 networks. * * @par Thread Sa

A detached coroutine. It would start to execute immediately and throws the exception it met. This could be used as the root of a coroutine execution c

Stat information for an executor. It contains the number of pending task for the executor now.
