Enum RedisTopology 

pub enum RedisTopology {
    Single,
    Sentinel,
    Cluster,
}

Redis deployment topology (SCALE-11, #248). Controls how the gateway connects to Redis for the distributed rate limiter, quotas, and shared cache. The default single mode uses one Redis URL (the existing behavior). sentinel mode resolves the master through a Sentinel deployment. cluster mode connects to a Redis Cluster.

Variants

Single

Single Redis instance (the default). Uses the url field directly. No HA — if the instance is down, the fail-open policy applies.

Sentinel

Redis Sentinel: resolves the master via the Sentinel nodes listed in nodes, using master_name to identify the monitored instance. The gateway connects to the resolved master via a ConnectionManager (automatic reconnection on failover is handled by re-resolving on disconnect).

Cluster

Redis Cluster: connects to the cluster via the node URLs in nodes (or url if nodes is empty). Uses the redis crate’s ClusterClient which handles slot mapping, MOVED/ASK redirections, and cross-slot routing automatically. Lua scripts use hash tags ({key}) to ensure all keys in a script land on the same slot.

Trait Implementations

impl Clone for RedisTopology

fn clone(&self) -> RedisTopology

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RedisTopology

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for RedisTopology

fn default() -> RedisTopology

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for RedisTopology

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for RedisTopology

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for RedisTopology

fn eq(&self, other: &RedisTopology) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for RedisTopology

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for RedisTopology

impl Eq for RedisTopology
