Struct AppStateInner 

#[non_exhaustive]
pub struct AppStateInner {
    pub config: Arc<Config>,
    pub db: Db,
    pub mailer: Mailer,
    pub queue: Queue,
    pub cache: Cache,
    pub storage: Storage,
    pub http: Http,
    /* private fields */
}

What an AppState holds. Apps read these as the state’s fields (state.db); only Renox builds one, at boot.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

config: Arc<Config>

The configuration.

db: Db

The database connection pool.

mailer: Mailer

Sends mail (MAIL_MAILER).

queue: Queue

Dispatches jobs.

cache: Cache

The cache (CACHE_STORE).

storage: Storage

The file storage disk (STORAGE_DISK).

http: Http

Calls other services; faked in tests (TestApp::fake_http).
