Module backoff 

Exponential backoff retry strategy

Provides configurable exponential backoff for connection retries and other network operations that may fail transiently.

Features

• Configurable initial delay, maximum delay, and retry limit
• Optional jitter (±30%) to prevent thundering herd
• Optional total duration limit (time-boxed retries)
• Custom multiplier support (default: 2.0)
• Iterator-based API for composability with async code

Example

use std::time::Duration;
use actr_framework::ExponentialBackoff;

// Basic usage — 5 retries with jitter
let backoff = ExponentialBackoff::builder()
    .initial_delay(Duration::from_millis(100))
    .max_delay(Duration::from_secs(30))
    .max_retries(5)
    .with_jitter()
    .build();

for delay in backoff {
    println!("waiting {:?}", delay);
}
