[−][src]Struct v4l::device::Info

pub struct Info { /* fields omitted */ }

Represents a video4linux device node

Implementations

impl Info[src]

pub fn new<P: AsRef<Path>>(path: P) -> Self[src]

Returns a device node observer by path

The device is opened in read only mode.

Arguments

  • path - Node path (usually a character device or sysfs entry)

Example

use v4l::device::Info;
let node = Info::new("/dev/video0");

pub fn path(&self) -> &Path[src]

Returns the absolute path of the device node

pub fn index(&self) -> Option<usize>[src]

Returns the index of the device node

pub fn name(&self) -> Option<String>[src]

Returns name of the device by parsing its sysfs entry
