Expand description

ServiceDiscovery is the interface to discover Backends.

Required Methods§

Source

fn discover<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<(BTreeSet<Backend>, HashMap<u64, bool>)>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Return the discovered collection of backends. And optionally whether these backends are enabled to serve or not in a HashMap. Any backend that is not explicitly in the set is considered enabled.
