Public Member Functions | |
CoCanRouterReadError () noexcept | |
Constructs a CAN error frame read operation. | |
ev::Executor | get_executor () const noexcept |
Returns the executor to which the completion task is (to be) submitted. | |
virtual void | operator() (const can_err *err, ::std::error_code ec) noexcept=0 |
The coroutine to be executed once the read operation completes (or is canceled). More... | |
![]() | |
void | restart () noexcept |
Resets the stackless coroutine so the next invocation starts at the beginning. | |
bool | is_ready () const noexcept |
Returns true if the stackless coroutine has finished. | |
bool | is_parent () const noexcept |
Returns true if the stackless coroutine is the parent of a fork. | |
bool | is_child () const noexcept |
Returns true if the stackless coroutine is the child of a fork. | |
Additional Inherited Members | |

pure virtualnoexcept |
The coroutine to be executed once the read operation completes (or is canceled).
err | a pointer to the received CAN error frame, or 0 on error (or if the operation is canceled). In the latter case, the error number is stored in ec. |
ec | the error code if err is 0. |
