Struct Device

pub struct Device<T: UsbContext> { /* private fields */ }

A reference to a USB device.

Implementations

impl<T: UsbContext> Device<T>

pub fn as_raw(&self) -> *mut libusb_device

Get the raw libusb_device pointer, for advanced use in unsafe code

pub fn context(&self) -> &T

Get the context associated with this device

pub unsafe fn from_libusb( context: T, device: NonNull<libusb_device>, ) -> Device<T>

Safety

Converts an existing libusb_device pointer into a Device<T>. device must be a pointer to a valid libusb_device. Rusb increments refcount.

pub fn device_descriptor(&self) -> Result<DeviceDescriptor>

Reads the device descriptor.

pub fn config_descriptor(&self, config_index: u8) -> Result<ConfigDescriptor>

Reads a configuration descriptor.

pub fn active_config_descriptor(&self) -> Result<ConfigDescriptor>

Reads the configuration descriptor for the current configuration.

pub fn bus_number(&self) -> u8

Returns the number of the bus that the device is connected to.

pub fn address(&self) -> u8

Returns the device’s address on the bus that it’s connected to.

pub fn speed(&self) -> Speed

Returns the device’s connection speed.

pub fn open(&self) -> Result<DeviceHandle<T>>

Opens the device.

pub fn port_number(&self) -> u8

Returns the device’s port number

pub fn get_parent(&self) -> Option<Self>

Returns the device’s parent

pub fn port_numbers(&self) -> Result<Vec<u8>, Error>

Get the list of all port numbers from root for the specified device

Trait Implementations

impl<T: UsbContext> Clone for Device<T>

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: UsbContext> Debug for Device<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T: UsbContext> Drop for Device<T>

fn drop(&mut self)

Releases the device reference.

impl<T: PartialEq + UsbContext> PartialEq for Device<T>

fn eq(&self, other: &Device<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
