Traits

• Hotplug
  When handling a Hotplug::device_arrived event it is considered safe to call any rusb function that takes a Device. It also safe to open a device and submit asynchronous transfers. However, most other functions that take a DeviceHandle are not safe to call. Examples of such functions are any of the synchronous API functions or the blocking functions that retrieve various USB descriptors. These functions must be used outside of the context of the Hotplug functions.
• UsbContext

Functions

• devices
  Returns a list of the current USB devices. Using global context
• disable_device_discovery
  Disable device scanning in libusb init.
• has_capability
  Tests whether the running libusb library supports capability API.
• has_hid_access
  Tests whether the running libusb library has HID access.
• has_hotplug
  Tests whether the running libusb library supports hotplug.
• open_device_with_vid_pid
  Convenience function to open a device by its vendor ID and product ID. Using global context
• request_type
  Builds a value for the bmRequestType field of a control transfer setup packet.
• set_log_level
  Sets the log level of a libusb global context.
• supports_detach_kernel_driver
  Tests whether the running libusb library supports detaching the kernel driver.
• version
  Returns a structure with the version of the running libusb library.

Type Aliases

• Result
  A result of a function that may return a Error.
