Struct RetryConfig 

pub struct RetryConfig {
    pub max_attempts: u32,
    pub initial_backoff_ms: u64,
    pub max_backoff_ms: u64,
    pub multiplier: f64,
    pub enable_jitter: bool,
}

Retry policy configuration

Examples

Using the default configuration:

use chie_shared::RetryConfig;

let config = RetryConfig::default();
assert_eq!(config.max_attempts, 3);
assert_eq!(config.initial_backoff_ms, 100);
assert_eq!(config.multiplier, 2.0);
assert!(config.enable_jitter);

// Check if retries are exhausted
assert!(!config.is_exhausted(0));
assert!(!config.is_exhausted(2));
assert!(config.is_exhausted(3));

Building a custom aggressive retry policy:

use chie_shared::RetryConfigBuilder;

let config = RetryConfigBuilder::new()
    .max_attempts(5)
    .initial_backoff_ms(100)
    .max_backoff_ms(10_000)
    .multiplier(2.0)
    .enable_jitter(false)
    .build();

assert_eq!(config.max_attempts, 5);
assert_eq!(config.initial_backoff_ms, 100);
assert!(!config.enable_jitter);

// Calculate backoff delays (without jitter) - exponential backoff
assert_eq!(config.next_backoff_ms(0), 100);   // 100 * 2^0
assert_eq!(config.next_backoff_ms(1), 200);   // 100 * 2^1
assert_eq!(config.next_backoff_ms(2), 400);   // 100 * 2^2
assert_eq!(config.next_backoff_ms(3), 800);   // 100 * 2^3

Fields

max_attempts: u32

Maximum number of retry attempts

initial_backoff_ms: u64

Initial backoff delay in milliseconds

max_backoff_ms: u64

Maximum backoff delay in milliseconds

multiplier: f64

Backoff multiplier (exponential)

enable_jitter: bool

Enable jitter to avoid thundering herd
