type Settings

type Settings struct {

	// Default is 5 minutes. -1 disables idle timeout check.
	IdleTimeout Duration `mapstructure:"idleTimeout"`
	// Frequency of idle checks made by idle connections reaper.
	// Default is 1 minute. -1 disables idle connections reaper,
	// but idle connections are still discarded by the client
	// if IdleTimeout is set.
	IdleCheckFrequency Duration `mapstructure:"idleCheckFrequency"`
	// The master name
	SentinelMasterName string `mapstructure:"sentinelMasterName"`
	// Use Redis Sentinel for automatic failover.
