Provided Methods

fn sentinel_get_master_addr_by_name<N>(
    &mut self,
    master_name: N
) -> PreparedCommand<'_, Self, Option<(String, u16)>>where
    Self: Sized,
    N: Into<BulkString>,

Return the ip and port number of the master with that name.

If a failover is in progress or terminated successfully for this master, it returns the address and port of the promoted replica.

Return

• None if sentinel does not know this master
• A tuple made up of
  • The IP of the master
  • The port of the master

fn sentinel_failover<N>(
    &mut self,
    master_name: N
) -> PreparedCommand<'_, Self, ()>where
    Self: Sized,
    N: Into<BulkString>,

Force a failover as if the master was not reachable, and without asking for agreement to other Sentinels (however a new version of the configuration will be published so that the other Sentinels will update their configurations).
