Trait Implementations

impl Default for RusbContext

fn default() -> RusbContext

Returns the “default value” for a type.

impl UsbContext for RusbContext

fn scan( &self, usb_vid: Option<u16>, usb_pid: Option<u16>, usb_protocol: Option<(u8, u8, u8)>, usb_serial: Option<&str>, ) -> Result<Vec<Box<dyn UsbDevice>>>

Scan the USB bus for devices matching VID/PID, and optionally also matching a serial number. This method always returns immediately with the list of currently plugged devices matching the requested criteria.

fn device_by_id( &self, usb_vid: u16, usb_pid: u16, usb_serial: Option<&str>, ) -> Result<Box<dyn UsbDevice>>

Find a device by VID:PID, and optionally disambiguate by serial number.

fn device_by_id_with_timeout( &self, usb_vid: u16, usb_pid: u16, usb_serial: Option<&str>, timeout: Duration, ) -> Result<Box<dyn UsbDevice>>

Find a device by VID:PID, and optionally disambiguate by serial number.

fn device_by_interface( &self, class: u8, subclass: u8, protocol: u8, usb_serial: Option<&str>, ) -> Result<Box<dyn UsbDevice>>

Find a device with a specific interface, and optionally disambiguate by serial number.

fn device_by_interface_with_timeout( &self, class: u8, subclass: u8, protocol: u8, usb_serial: Option<&str>, timeout: Duration, ) -> Result<Box<dyn UsbDevice>>

Find a device with a specific interface, and optionally disambiguate by serial number.
