Struct AppState 

pub struct AppState {
    pub pool: PgPool,
    pub read_only: bool,
    pub cache: DashboardCache,
    pub callback_hmac_secret: Option<[u8; 32]>,
    pub poll_interval_ms: u64,
    pub metrics: AwaMetrics,
}

Fields

pool: PgPool

read_only: bool

cache: DashboardCache

callback_hmac_secret: Option<[u8; 32]>

poll_interval_ms: u64

Suggested frontend poll interval — at least as long as the cache TTL so clients don’t poll faster than the cache can refresh.

metrics: AwaMetrics

Cached AwaMetrics handle. AwaMetrics::from_global() rebuilds the full instrument set on every call, so we construct it once here and share it across request handlers.

Implementations

impl AppState

pub fn new( pool: PgPool, read_only: bool, cache_ttl: Duration, callback_hmac_secret: Option<[u8; 32]>, ) -> Self

pub fn require_writable(&self) -> Result<(), ApiError>

pub fn invalidate_dashboard_caches(&self)

UI mutations change multiple dashboard surfaces, and the server caches those aggregate endpoints independently. Invalidate them as a unit so follow-up reads do not serve stale queue/job state after a mutation.

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.
