Struct redis::sentinel::Sentinel

pub struct Sentinel { /* private fields */ }

The Sentinel type, serves as a special purpose client which builds other clients on demand.

Implementations

impl Sentinel

pub fn build<T: IntoConnectionInfo>(params: Vec<T>) -> RedisResult<Sentinel>

Creates a Sentinel client performing some basic checks on the URLs that might make the operation fail.

pub fn master_for( &mut self, service_name: &str, node_connection_info: Option<&SentinelNodeConnectionInfo> ) -> RedisResult<Client>

Determines the masters address for the given name, and returns a client for that master.

pub fn replica_for( &mut self, service_name: &str, node_connection_info: Option<&SentinelNodeConnectionInfo> ) -> RedisResult<Client>

Connects to a randomly chosen replica of the given master name.

pub fn replica_rotate_for( &mut self, service_name: &str, node_connection_info: Option<&SentinelNodeConnectionInfo> ) -> RedisResult<Client>

Attempts to connect to a different replica of the given master name each time. There is no guarantee that we’ll actually be connecting to a different replica in the next call, but in a static set of replicas (no replicas added or removed), on average we’ll choose each replica the same number of times.

impl Sentinel

pub async fn async_master_for( &mut self, service_name: &str, node_connection_info: Option<&SentinelNodeConnectionInfo> ) -> RedisResult<Client>

Determines the masters address for the given name, and returns a client for that master.

pub async fn async_replica_for( &mut self, service_name: &str, node_connection_info: Option<&SentinelNodeConnectionInfo> ) -> RedisResult<Client>

Connects to a randomly chosen replica of the given master name.

pub async fn async_replica_rotate_for<'a>( &mut self, service_name: &str, node_connection_info: Option<&SentinelNodeConnectionInfo> ) -> RedisResult<Client>

Attempts to connect to a different replica of the given master name each time. There is no guarantee that we’ll actually be connecting to a different replica in the next call, but in a static set of replicas (no replicas added or removed), on average we’ll choose each replica the same number of times.
