[−][src]Struct libusb::Context
A libusb context.
Methods
impl Context[src]
impl Contextpub fn new() -> Result<Self>[src]
pub fn new() -> Result<Self>Opens a new libusb context.
pub fn set_log_level(&mut self, level: LogLevel)[src]
pub fn set_log_level(&mut self, level: LogLevel)Sets the log level of a libusb context.
pub fn has_capability(&self) -> bool[src]
pub fn has_capability(&self) -> boolpub fn has_hotplug(&self) -> bool[src]
pub fn has_hotplug(&self) -> boolTests whether the running libusb library supports hotplug.
pub fn has_hid_access(&self) -> bool[src]
pub fn has_hid_access(&self) -> boolTests whether the running libusb library has HID access.
pub fn supports_detach_kernel_driver(&self) -> bool[src]
pub fn supports_detach_kernel_driver(&self) -> boolTests whether the running libusb library supports detaching the kernel driver.
pub fn devices<'a>(&'a self) -> Result<DeviceList<'a>>[src]
pub fn devices<'a>(&'a self) -> Result<DeviceList<'a>>Returns a list of the current USB devices. The context must outlive the device list.
pub fn open_device_with_vid_pid<'a>(
&'a self,
vendor_id: u16,
product_id: u16
) -> Option<DeviceHandle<'a>>[src]
pub fn open_device_with_vid_pid<'a>(
&'a self,
vendor_id: u16,
product_id: u16
) -> Option<DeviceHandle<'a>>Convenience function to open a device by its vendor ID and product ID.
This function is provided as a convenience for building prototypes without having to
iterate a DeviceList. It is not meant for production
applications.
Returns a device handle for the first device found matching vendor_id and product_id.
On error, or if the device could not be found, it returns None.
