Enum LoadBalancingAlgorithms 

#[repr(i32)]
pub enum LoadBalancingAlgorithms {
    RoundRobin = 0,

Variants

RoundRobin = 0

Random = 1

LeastLoaded = 2

PowerOfTwo = 3

Hrw = 4

Highest-Random-Weight / rendezvous hashing — client-affine backend selection. Maps a client key (on UDP the source IP, or source IP and port per UdpAffinityKey; the source IP, or the cluster’s affinity_header / affinity_cookie, on HTTP, HTTPS and TCP) to a backend that survives minimal disruption on backend add/remove.

Maglev = 5

Maglev consistent hashing — precomputed lookup table for even, stable backend distribution across the same client keyspace as HRW.

Implementations

impl LoadBalancingAlgorithms

pub const fn is_valid(value: i32) -> bool

Returns true if value is a variant of LoadBalancingAlgorithms.

pub fn from_i32(value: i32) -> Option<LoadBalancingAlgorithms>

👎Deprecated:

Use the TryFrom<i32> implementation instead

Converts an i32 to a LoadBalancingAlgorithms, or None if value is not a valid variant.

impl LoadBalancingAlgorithms

pub fn as_str_name(&self) -> &'static str

String value of the enum field names used in the ProtoBuf definition.

The values are not transformed in any way and thus are considered stable (if the ProtoBuf definition does not change) and safe for programmatic use.

pub fn from_str_name(value: &str) -> Option<Self>

Creates an enum from field names used in the ProtoBuf definition.
