Struct Device

pub struct Device { /* private fields */ }

A HID device that was detected by calling HidBackend::enumerate

Implementations

impl Device

pub fn to_device_info(self) -> DeviceInfo

pub async fn open_readable(&self) -> HidResult<DeviceReader>

Open the device in read-only mode

pub async fn open_writeable(&self) -> HidResult<DeviceWriter>

Open the device in write-only mode Note: Not all backends support this mode and might upgrade the permission to read+write behind the scenes

pub async fn open(&self) -> HidResult<DeviceReaderWriter>

Open the device in read and write mode

Methods from Deref<Target = DeviceInfo>

pub fn matches( &self, usage_page: u16, usage_id: u16, vendor_id: u16, product_id: u16, ) -> bool

Convenience method for easily finding a specific device

Trait Implementations

impl Debug for Device

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

Formats the value using the given formatter.

impl Deref for Device

type Target = DeviceInfo

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl Hash for Device

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Device

fn eq(&self, other: &Self) -> 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.
