experimental::generator

A generator is a coro that returns void and yields value.

typedef coro< T, void, Executor, Allocator > generator;

Types

Name	Description
allocator_type	The allocator type.
completion_handler	Completion handler type used by async_resume.
error_type	The error type of the coroutine. Void for noexcept.
executor_type	The executor type.
input_type	The value that can be passed into a symmetrical cororoutine. void if asymmetrical.
promise_type	The internal promise-type of the coroutine.
result_type	The type received by a co_await or async_resume. Its a combination of yield and return.
return_type	The type that can be passed out through a co_return.
signature_type	The signature used by the async_resume.
traits	The traits of the coroutine. See asio::experimental::coro_traits for details.
yield_type	The type that can be passed out through a co_yield.

Member Functions

Name	Description
async_resume	Resume the coroutine.
coro [constructor]	The default constructor, gives an invalid coroutine. — Move constructor. —
get_allocator	Get the used allocator.
get_executor	Get the used executor.
is_open	Check whether the coroutine is open, i.e. can be resumed.
operator bool	Check whether the coroutine is open, i.e. can be resumed.
operator co_await	Operator used for coroutines without input value.
operator()	Operator used for coroutines with input value.
operator=	Move assignment.
~coro [destructor]	Destructor. Destroys the coroutine, if it holds a valid one.

Data Members

Name	Description
is_noexcept [static]	Whether or not the coroutine is noexcept.

Template parameter Yield specifies type or signature used by co_yield, Return specifies the type used for co_return, and Executor specifies the underlying executor type.
