Struct DeviceProfile 

pub struct DeviceProfile {
    pub kind: Symbol,
    pub tier: DeviceTier,
    pub display: Vec<Symbol>,
    pub input: Vec<Symbol>,
    pub output: Vec<Symbol>,
    pub links: Vec<Symbol>,
    pub streams: Vec<Symbol>,
    pub rate: RateClass,
    pub policy: Expr,
}

A typed device envelope derived from SurfaceCaps.

This is capability data, not a concrete device enum. Instances advertise maps; this profile reads them into stable lanes so routing and degradation decisions share one interpretation.

Fields

kind: Symbol

Device family token, for example watch, glasses, or desktop.

tier: DeviceTier

Tier computed by derive_tier.

display: Vec<Symbol>

Display capability tokens such as flat, stereo, round, or hud.

input: Vec<Symbol>

Input capability tokens such as touch, tap, voice, or crown.

output: Vec<Symbol>

Output capability tokens such as screen, haptic, speaker, or hud.

links: Vec<Symbol>

Link tokens such as usb, phone-relay, or lan-ws.

streams: Vec<Symbol>

Stream tokens such as pose, heart-rate, motion, or battery.

rate: RateClass

Declared timing envelope.

policy: Expr

Consent, retention, and redaction hints.

Implementations

impl DeviceProfile

pub fn new(parts: DeviceProfileParts) -> Self

Builds a profile and computes the tier from the advertised fields.

pub fn from_surface_caps(caps: &SurfaceCaps) -> Self

Derives a device profile from open SurfaceCaps metadata.

pub fn to_expr(&self) -> Expr

Encodes this profile as a device/profile tagged map.

pub fn from_expr(expr: &Expr) -> Result<Self, DeviceProfileError>

Parses a device/profile tagged map.

impl DeviceProfile

pub fn to_surface_caps(&self, client_id: impl Into<String>) -> SurfaceCaps

Converts this profile back into open surface capabilities for client_id.

This is the bridge used by device peers: the device keeps the typed profile for routing and tier decisions, while the synchronized surface hub receives ordinary SurfaceCaps and continues to project scenes by open capability metadata.

Trait Implementations

impl Clone for DeviceProfile

fn clone(&self) -> DeviceProfile

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

Performs copy-assignment from source.

impl Debug for DeviceProfile

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

Formats the value using the given formatter.

impl PartialEq for DeviceProfile

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

Equality operator ==.
