Struct AppState 

pub struct AppState {
    pub storage: Arc<dyn Storage>,
    pub declared_kbs: Arc<BTreeMap<String, KbSlug>>,
    pub access_policies: Arc<BTreeMap<String, Arc<AccessPolicy>>>,
    pub bearer_token: Arc<String>,
    pub max_body_size: u64,
    pub max_patchable_size: u64,
    pub indexer_tx: Sender<IndexEvent>,
    pub searcher: Arc<dyn Searcher>,
}

Application state shared across all axum handlers.

This is cloned cheaply for each request (all fields are behind Arc).

Fields

storage: Arc<dyn Storage>

The backing storage implementation (injected at startup).

declared_kbs: Arc<BTreeMap<String, KbSlug>>

Canonical map of slug string → KbSlug for declared knowledge bases.

access_policies: Arc<BTreeMap<String, Arc<AccessPolicy>>>

Startup snapshot of manifest access policies, keyed by KB slug.

One Arc per policy so a request-scoped authorization handle can hold its knowledge base’s policy cheaply instead of borrowing the whole map.

bearer_token: Arc<String>

Static Bearer token for authenticating API requests.

max_body_size: u64

Maximum accepted PUT body size in bytes (16 MiB in M2).

max_patchable_size: u64

Maximum object size eligible for patch operations, in bytes.

indexer_tx: Sender<IndexEvent>

Sender half of the async indexing queue.

searcher: Arc<dyn Searcher>

The search implementation (injected at startup).

Trait Implementations

impl Clone for AppState

fn clone(&self) -> AppState

Returns a duplicate of the value.

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