Public Member Functions
auto	start (libusb_context *usb_ctx, std::stop_token stop) -> bool
	Start the libusb event processing loop.
auto	ref () noexcept
	Increment internal reference count.
auto	unref () noexcept
	Decrement internal reference count.
auto	stop ()
	Stop the event loop and wait for the thread to finish.
	~trivial_event_handler ()
	Stop the event thread on destruction.

Detailed Description

Trivial single-threaded libusb event handler.

This handler starts a background loop that repeatedly calls libusb_handle_events_timeout() until std::stop_token requests stop.

Constructor & Destructor Documentation

~trivial_event_handler()

co_usb::ev::trivial_event_handler::~trivial_event_handler ( )

inline

Stop the event thread on destruction.

Member Function Documentation

ref()

auto co_usb::ev::trivial_event_handler::ref ( )

inlinenoexcept

Increment internal reference count.

This implementation is a no-op.

start()

auto co_usb::ev::trivial_event_handler::start ( libusb_context *  usb_ctx, std::stop_token  stop  ) -> bool

inline

Start the libusb event processing loop.

Parameters

usb_ctx	libusb context to handle events for.
stop	Stop token used to end the loop.

Returns

true on successful start.

stop()

auto co_usb::ev::trivial_event_handler::stop ( )

inline

Stop the event loop and wait for the thread to finish.

Must block until handling is stopped.

unref()

auto co_usb::ev::trivial_event_handler::unref ( )

inlinenoexcept

Decrement internal reference count.

This implementation is a no-op.
