Struct RedisSentinelBuilder 

pub struct RedisSentinelBuilder { /* private fields */ }

Builder for a Redis Sentinel topology.

Example

use redis_server_wrapper::RedisSentinel;

let sentinel = RedisSentinel::builder()
    .master_name("mymaster")
    .master_port(6390)
    .replicas(2)
    .sentinels(3)
    .start()
    .await
    .unwrap();

assert!(sentinel.is_healthy().await);

Implementations

impl RedisSentinelBuilder

pub fn master_name(self, name: impl Into<String>) -> Self

Set the name of the monitored master (default: "mymaster").

pub fn master_port(self, port: u16) -> Self

Set the master’s port (default: 6390).

pub fn replicas(self, n: u16) -> Self

Set the number of replicas to start (default: 2).

pub fn replica_base_port(self, port: u16) -> Self

Set the base port for replica nodes (default: 6391).

Replicas are assigned consecutive ports starting at this value.

pub fn sentinels(self, n: u16) -> Self

Set the number of sentinel processes to start (default: 3).

pub fn sentinel_base_port(self, port: u16) -> Self

Set the base port for sentinel processes (default: 26389).

Sentinels are assigned consecutive ports starting at this value.

pub fn quorum(self, q: u16) -> Self

Set the quorum count — how many sentinels must agree before a failover is triggered (default: 2).

pub fn bind(self, bind: impl Into<String>) -> Self

Set the bind address for all processes in the topology (default: "127.0.0.1").

pub fn logfile(self, path: impl Into<String>) -> Self

Set the log file path for all processes in the topology.

pub fn down_after_ms(self, ms: u64) -> Self

Set the down-after-milliseconds threshold for all monitored masters (default: 5000).

A master is considered down after it fails to respond within this many milliseconds.

pub fn failover_timeout_ms(self, ms: u64) -> Self

Set the failover-timeout for all monitored masters in milliseconds (default: 10000).

pub fn extra(self, key: impl Into<String>, value: impl Into<String>) -> Self

Set an arbitrary config directive for all processes in the topology.

pub fn redis_server_bin(self, bin: impl Into<String>) -> Self

Set a custom redis-server binary path.

pub fn redis_cli_bin(self, bin: impl Into<String>) -> Self

Set a custom redis-cli binary path.

pub fn monitor( self, name: impl Into<String>, host: impl Into<String>, port: u16, ) -> Self

Add an additional master for the sentinels to monitor.

The builder-managed topology still creates the primary master configured by Self::master_name and Self::master_port. Additional monitored masters are expected to already be running.

pub fn monitor_with_replicas( self, name: impl Into<String>, host: impl Into<String>, port: u16, expected_replicas: u16, ) -> Self

Add an additional master and the minimum number of replicas expected for it.

pub async fn start(self) -> Result<RedisSentinelHandle>

Start the full topology: master, replicas, sentinels.
