Required Methods

fn source_label(&self) -> String

Human-readable description of where config is loaded from, for logs.

fn maybe_reload<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Option<ConfigState>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Return a freshly loaded state if a reload is needed; otherwise, return None.

fn reload_now<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<ConfigState>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Force a reload, regardless of whether a change was detected.
