Struct AppState 

pub struct AppState {
    pub server_host: String,
    pub server_port: String,
    pub export_dir: String,
    pub devices: Vec<DeviceState>,
    pub selected_device_ids: Vec<String>,
    pub transient: TransientUiState,
    pub events: Vec<String>,
    /* private fields */
}

Full application state.

This is the single source of truth for all UI-visible data.

Fields

server_host: String

server_port: String

export_dir: String

Directory where locally-recorded Parquet exports are written.

devices: Vec<DeviceState>

selected_device_ids: Vec<String>

Devices currently selected for the detail tabs. Multiple devices can be selected at once for side-by-side (FDM mesh) collection.

transient: TransientUiState

events: Vec<String>

Implementations

impl AppState

pub fn with_defaults() -> Self

Construct default state with localhost webserver settings.

pub fn push_intent(&mut self, intent: UserIntent)

Queue one user intent.

pub fn push_device_action( &mut self, id: impl Into<String>, action: DeviceAction, )

Queue a per-device action addressed to id.

pub fn drain_intents(&mut self) -> Vec<UserIntent>

Drain queued intents in FIFO order.

pub fn push_event(&mut self, message: impl Into<String>)

Append one event line to the global event history.

pub fn selected_indices(&self) -> Vec<usize>

Indices of the currently selected devices, in devices order (so the detail tabs render columns in a stable order regardless of click order).

pub fn is_selected(&self, id: &str) -> bool

Whether the device with the given id is currently selected.

pub fn toggle_selection(&mut self, id: String)

Toggle membership of id in the selection set.

pub fn device_index_by_id(&self, id: &str) -> Option<usize>

Index of the device with the given id.

pub fn device_mut_by_id(&mut self, id: &str) -> Option<&mut DeviceState>

Mutable reference to the device with the given id.

pub fn base_http_url(&self) -> String

Build the HTTP base URL from host/port fields.

pub fn device_ws_url(&self, id: &str) -> String

Build the per-device WebSocket stream URL.

pub fn reconcile_devices( &mut self, entries: Vec<DeviceListEntry>, ) -> ReconcileOutcome

Reconcile a fresh GET /api/devices payload into per-device state.

Adds new devices (default forms), refreshes live status on existing ones, drops devices that vanished, and auto-selects the first device when the current selection is empty or stale.

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 Debug for AppState

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