Struct EconomicIndicator 

pub struct EconomicIndicator { /* private fields */ }

A macro-economic data series backed by configured data providers.

Created via Providers::economic.

Implementations

impl EconomicIndicator

pub fn cache(self, ttl: Duration) -> Self

Cache responses for ttl instead of the default 60 seconds, deduplicating concurrent identical requests.

pub fn cache_forever(self) -> Self

Cache responses for the handle’s lifetime instead of the default 60 seconds.

pub fn no_cache(self) -> Self

Disable caching — every call fetches fresh data.

pub fn series_id(&self) -> &str

The handle’s identifier string.

impl EconomicIndicator

pub async fn series(&self) -> Result<EconomicSeries>

Fetch the full data series for this economic indicator.

pub async fn as_of(&self, date: &str) -> Result<EconomicSeries>

Fetch this series as it stood on date (YYYY-MM-DD) instead of as currently revised (FRED only, via ALFRED’s realtime window).

Macro data is revised after publication, so backtesting a rule against today’s series is look-ahead bias: the values it trades on were not knowable at the time. This returns the vintage actually published as of date. Cached per date.
