Struct WaitStrategyConfig 

pub struct WaitStrategyConfig<T> {
    pub max_attempts: Option<usize>,
    pub initial_delay: Duration,
    pub max_delay: Duration,
    pub backoff_rate: f64,
    pub jitter: JitterStrategy,
    pub should_continue_polling: Box<dyn Fn(&T) -> bool + Send + Sync>,
}

Configuration for creating a wait strategy.

This struct holds all the parameters needed to build a wait strategy function via create_wait_strategy. The resulting function can be used with WaitForConditionConfig to control polling behavior with backoff, jitter, and a custom predicate.

Type Parameters

• T: The state type returned by the condition check function.

Example

use durable_execution_sdk::config::{WaitStrategyConfig, JitterStrategy, create_wait_strategy, WaitDecision};
use durable_execution_sdk::Duration;

let config = WaitStrategyConfig {
    max_attempts: Some(10),
    initial_delay: Duration::from_seconds(5),
    max_delay: Duration::from_seconds(300),
    backoff_rate: 1.5,
    jitter: JitterStrategy::Full,
    should_continue_polling: Box::new(|state: &String| state != "COMPLETED"),
};

let strategy = create_wait_strategy(config);
// strategy(&"COMPLETED".to_string(), 1) => WaitDecision::Done

Fields

max_attempts: Option<usize>

Maximum number of polling attempts. None defaults to 60.

initial_delay: Duration

Initial delay between polls.

max_delay: Duration

Maximum delay cap.

backoff_rate: f64

Backoff multiplier applied per attempt.

jitter: JitterStrategy

Jitter strategy applied to the computed delay.

should_continue_polling: Box<dyn Fn(&T) -> bool + Send + Sync>

Predicate that returns true if polling should continue, false if the condition is met.
