设备基本信息

Fields

name: String

对用户友好的显示名称 (e.g. “Logitech C920”)

id: String

唯一硬件 ID (e.g. “/dev/video0” 或 USB 序列号) 用于 Driver::open 的参数

backend: String

后端类型标识 (e.g. “V4L2”, “MediaFoundation”)

bus_info: Option<String>

硬件总线信息 (可选，e.g. “usb-0000:00:14.0-1”) 用于高级拓扑识别

Trait Implementations

impl Clone for DeviceInfo

fn clone(&self) -> DeviceInfo

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DeviceInfo

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for DeviceInfo

fn eq(&self, other: &DeviceInfo) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
