Struct DeviceIdentity 

pub struct DeviceIdentity {
    pub display_name: String,
    pub kind: DeviceKind,
    pub capabilities: Capabilities,
}

Last-known identity of a device, captured while it was online so the UI can render its card and the correct config panels before any live HID++ probe completes — or while the device is asleep and can’t be probed at all.

Every field is a static property of the model, not of the current connection: an MX Master 3S has adjustable DPI whether or not it is awake. That is what makes this safe to persist — it never goes stale. It is also free of any per-unit identifier (no serial number, no unit id), so caching it adds no privacy surface beyond the config_key already used as the map key. Persisting identity is what stops a sleeping/just-booted mouse from vanishing from the device list (and losing its Pointer/Buttons panels) until a cold probe happens to win its race — see issue #159.

Fields

display_name: String

The name shown in the carousel, as resolved from the asset registry the last time the device was online.

kind: DeviceKind

The device’s resolved DeviceKind (asset registry preferred, HID++ classification as fallback).

capabilities: Capabilities

Configuration capabilities measured from the device’s HID++ feature table. This is the field that keeps a sleeping mouse’s panels visible.

Trait Implementations

impl Clone for DeviceIdentity

fn clone(&self) -> DeviceIdentity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DeviceIdentity

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DeviceIdentity

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for DeviceIdentity

impl PartialEq for DeviceIdentity

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

impl Serialize for DeviceIdentity

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
