Struct AppState 

pub struct AppState {
    pub graph: Arc<RwLock<AeoGraph>>,
    pub audit_client: Client,
}

Shared app state — a single graph protected by a RwLock so /ingest can replace it atomically without blocking concurrent reads.

When built with the audit-stream feature (default), the state also holds a reqwest::Client reused for governance-event emission. The client itself is cheap; what matters is reusing connections so a burst of ingests doesn’t open one TCP socket per emit.

Fields

graph: Arc<RwLock<AeoGraph>>

The graph itself.

audit_client: Client

Shared HTTP client for audit_stream::emit. Always present when the feature is on, even if AUDIT_STREAM_URL is unset (in which case emit no-ops without using it).

Implementations

impl AppState

pub fn new() -> Self

Construct fresh empty state with a default audit-stream client.

pub fn with_audit_client(audit_client: Client) -> Self

Build state with a caller-provided audit-stream client. Tests use this to swap in a wiremock-backed client.

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.
