Struct RetryConfig 

pub struct RetryConfig {
    pub max_attempts: u32,
    pub initial_delay: Duration,
    pub max_delay: Duration,
    pub multiplier: f64,
    pub max_duration: Duration,
    pub jitter: bool,
}

Configuration for retry logic

Defines the parameters for exponential backoff retry behavior when connecting to PostgreSQL or recovering from transient failures.

Example

use pg_walstream::RetryConfig;
use std::time::Duration;

// Use default configuration (5 attempts, 1s to 60s delays)
let config = RetryConfig::default();

// Or create custom configuration
let custom_config = RetryConfig {
    max_attempts: 10,
    initial_delay: Duration::from_millis(500),
    max_delay: Duration::from_secs(30),
    multiplier: 2.0,
    max_duration: Duration::from_secs(600),
    jitter: true,
};

Fields

max_attempts: u32

Maximum number of retry attempts before giving up

initial_delay: Duration

Initial delay before the first retry

max_delay: Duration

Maximum delay between retries (caps exponential growth)

multiplier: f64

Multiplier for exponential backoff (typically 2.0)

max_duration: Duration

Maximum total duration for all retry attempts

jitter: bool

Whether to add random jitter to delays (reduces thundering herd)
