    // Required method
    fn reload<'life0, 'life1, 'async_trait>(
        &'life0 self,
        state: &'life1 S,
    ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait,

    fn priority(&self) -> Option<u8> { ... }
}

Anything that can hot-reload itself when config changes.

reload() is the same shape as Provider::boot() — re-read the on-disk config (use tokio::fs, never std::fs in this async path) and rebuild the runtime snapshot, publishing it through an ArcSwap so in-flight requests/connections see the swap atomically. Reload must NOT change which providers are registered; it only refreshes state of an already-registered provider.

Required Methods

fn reload<'life0, 'life1, 'async_trait>( &'life0 self, state: &'life1 S, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Perform a synchronous reload using the current shared state. Implementations may spawn async work internally if needed.

Provided Methods

fn priority(&self) -> Option<u8>

Optional reload priority.

Lower values run earlier among otherwise-ready providers. None means priority::NORMAL. Prefer Provider::order() for real dependency relationships.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
