Struct WeightedStrategy 

pub struct WeightedStrategy;

Selects a healthy proxy with probability proportional to its weight.

Proxies with weight == 0 are never selected.

Example

use stygian_proxy::strategy::{WeightedStrategy, RotationStrategy, ProxyCandidate};
use stygian_proxy::types::ProxyMetrics;
use std::sync::Arc;
use uuid::Uuid;

let strategy = WeightedStrategy;
let candidates = vec![
    ProxyCandidate { id: Uuid::new_v4(), weight: 10, metrics: Arc::new(ProxyMetrics::default()), healthy: true },
    ProxyCandidate { id: Uuid::new_v4(), weight: 1,  metrics: Arc::new(ProxyMetrics::default()), healthy: true },
];
strategy.select(&candidates).await.unwrap();
