[−][src]Trait cueball::resolver::Resolver
Cueball backend resolver
Resolvers identify the available backends (i.e. nodes) providing a
service and relay information about those backends to the connection
pool. Resolvers should also inform the connection pool when a backend is no longer
available so that the pool can rebalance the connections on the remaining
backends.
Required methods
fn run(&mut self, s: Sender<BackendMsg>)
Start the operation of the resolver. Begin querying for backends and
notifying the connection pool using the provided Sender.
This function is expected to block while the resolver is running, and return if the receiving end of the channel is closed, or if the Resolver encounters an unrecoverable error of any sort. Thus, callers can shut down the resolver by closing the receiving end of the channel.
