}

High level representation of response to the ROLE command.

Variants

Primary

Represents a primary role, which is master in legacy Redis terminology.

Fields

replication_offset: u64

The current primary replication offset

replicas: Vec<ReplicaInfo>

List of replica, each represented by a tuple of IP, port and the last acknowledged replication offset.

Replica

Represents a replica role, which is slave in legacy Redis terminology.

Fields

primary_ip: String

The IP of the primary.

primary_port: u16

The port of the primary.

replication_state: String

The state of the replication from the point of view of the primary.

data_received: u64

The amount of data received from the replica so far in terms of primary replication offset.

Sentinel

Represents a sentinel role.

Fields

primary_names: Vec<String>

List of primary names monitored by this Sentinel instance.

Trait Implementations

impl Clone for Role

fn clone(&self) -> Role

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Role

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

Formats the value using the given formatter.

impl FromRedisValue for Role

fn from_redis_value(v: &Value) -> RedisResult<Self>

Given a redis Value this attempts to convert it into the given destination type. If that fails because it’s not compatible an appropriate error is generated.

fn from_owned_redis_value(v: Value) -> RedisResult<Self>

Given a redis Value this attempts to convert it into the given destination type. If that fails because it’s not compatible an appropriate error is generated.

fn from_redis_values(items: &[Value]) -> RedisResult<Vec<Self>>

Similar to from_redis_value but constructs a vector of objects from another vector of values. This primarily exists internally to customize the behavior for vectors of tuples.

fn from_owned_redis_values(items: Vec<Value>) -> RedisResult<Vec<Self>>

The same as from_redis_values, but takes a Vec<Value> instead of a &[Value].

fn from_byte_vec(_vec: &[u8]) -> Option<Vec<Self>>

Convert bytes to a single element vector.

fn from_owned_byte_vec(_vec: Vec<u8>) -> RedisResult<Vec<Self>>

Convert bytes to a single element vector.

impl PartialEq for Role

fn eq(&self, other: &Role) -> 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.
