Struct Capabilities 

Source 
pub struct Capabilities(/* private fields */);
Expand description

Stores generic device information.

Returned by Device::capabilities.

Implementations§

Source§

impl Capabilities

Source

pub fn driver(&self) -> &str

Returns the identifier of the V4L2 driver that provides this device.

Examples:

  • uvcvideo
  • v4l2 loopback
Source

pub fn card(&self) -> &str

Returns the card or device name.

For v4l2loopback devices, the reported card name can be configured by passing the card_label parameter when loading the module (or via modprobe.d).

Source

pub fn bus_info(&self) -> &str

Returns a description of where on the system the device is attached.

Examples:

  • usb-0000:0a:00.3-2.1
  • platform:v4l2loopback-002
Source

pub fn all_capabilities(&self) -> CapabilityFlags

Returns all capabilities the underlying hardware device exposes.

Some capabilities might be inaccessible through the opened device node and require opening a different one.

Source

pub fn device_capabilities(&self) -> CapabilityFlags

Returns the capabilities available through the currently opened device node.
