[−][src]Struct libusb_wishbone_tool::Context
A libusb
context.
Implementations
impl Context
[src]
pub fn new() -> Result<Self>
[src]
Opens a new libusb
context.
pub fn set_log_level(&mut self, level: LogLevel)
[src]
Sets the log level of a libusb
context.
pub fn has_capability(&self) -> bool
[src]
pub fn has_hotplug(&self) -> bool
[src]
Tests whether the running libusb
library supports hotplug.
pub fn has_hid_access(&self) -> bool
[src]
Tests whether the running libusb
library has HID access.
pub fn supports_detach_kernel_driver(&self) -> bool
[src]
Tests whether the running libusb
library supports detaching the kernel driver.
pub fn devices<'a>(&'a self) -> Result<DeviceList<'a>>
[src]
Returns a list of the current USB devices. The context must outlive the device list.
pub fn open_device_with_vid_pid(
&self,
vendor_id: u16,
product_id: u16
) -> Option<DeviceHandle>
[src]
&self,
vendor_id: u16,
product_id: u16
) -> Option<DeviceHandle>
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
.
pub fn register_callback(
&self,
vendor_id: Option<u16>,
product_id: Option<u16>,
class: Option<u8>,
callback: Box<dyn Hotplug>
) -> Result<Registration>
[src]
&self,
vendor_id: Option<u16>,
product_id: Option<u16>,
class: Option<u8>,
callback: Box<dyn Hotplug>
) -> Result<Registration>
pub fn unregister_callback(&self, reg: Registration)
[src]
TODO: fix handler leak
pub fn handle_events(&self, timeout: Option<Duration>) -> Result<()>
[src]
