Struct AppState 

pub struct AppState {
    pub devices: Arc<DeviceRegistry>,
}

Shared application state, cheaply cloned into every route handler via Axum’s State extractor. Holds only the device registry; all per-device state lives behind DeviceRegistry.

Fields

devices: Arc<DeviceRegistry>

Implementations

impl AppState

pub fn new() -> Self

Empty registry with the default no-op StandardCsiProfile; populate via DeviceRegistry::attach or crate::supervisor::run_supervisor.

pub fn with_profile(profile: Arc<dyn CsiProfile>) -> Self

Empty registry whose devices carry a custom capability CsiProfile. An embedder supplies its own profile to extend the accepted protocols, CSI presets, and data_format labels.

pub fn profile(&self) -> &Arc<dyn CsiProfile>

The capability profile shared by this state’s devices.

Trait Implementations

impl Clone for AppState

fn clone(&self) -> AppState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for AppState

fn default() -> Self

Returns the “default value” for a type.

impl FromRequestParts<AppState> for Device

type Rejection = (StatusCode, Json<ApiResponse>)

If the extractor fails it’ll use this “rejection” type. A rejection is a kind of error that can be converted into a response.

async fn from_request_parts( parts: &mut Parts, state: &AppState, ) -> Result<Self, Self::Rejection>

Perform the extraction.
