Enum PlbStrategy 

pub enum PlbStrategy {
    RoundRobin,
    WeightedRandom,
    LeastConnections,
    LeastLatency,
    ConsistentHash,
    PowerOfTwo,
}

Load-balancing selection strategy.

Variants

RoundRobin

Simple round-robin over healthy peers.

WeightedRandom

Weighted random selection proportional to peer weight.

LeastConnections

Always select the peer with fewest in-flight requests.

LeastLatency

Always select the peer with lowest average latency.

ConsistentHash

FNV-1a consistent hash on the request key with virtual nodes.

PowerOfTwo

Sample two random healthy peers and pick the better one.

Trait Implementations

impl Clone for PlbStrategy

fn clone(&self) -> PlbStrategy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for PlbStrategy

impl Debug for PlbStrategy

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

Formats the value using the given formatter.

impl Default for PlbStrategy

fn default() -> PlbStrategy

Returns the “default value” for a type.

impl Eq for PlbStrategy

impl PartialEq for PlbStrategy

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