Struct RetryConfig 

pub struct RetryConfig {
    pub max_retries: u32,
    pub base_delay_ms: u64,
    pub max_delay_ms: u64,
    pub backoff_multiplier: f64,
    pub jitter: bool,
}

Configuration for retry logic with exponential backoff.

RetryConfig defines the parameters for retrying failed operations, such as the maximum number of retries and the delay between attempts.

Fields

max_retries: u32

The maximum number of retry attempts to make.

base_delay_ms: u64

The base delay between retries, in milliseconds. This is the starting point for the exponential backoff calculation.

max_delay_ms: u64

The maximum possible delay between retries, in milliseconds.

backoff_multiplier: f64

The multiplier for the exponential backoff. Each subsequent delay is multiplied by this factor.

jitter: bool

A flag indicating whether to add a random jitter to the delay time. Jitter helps to prevent a “thundering herd” problem in distributed systems.

Implementations

impl RetryConfig

pub fn new(max_retries: u32) -> Self

Creates a new RetryConfig with a specified maximum number of retries and default values for other settings.

Arguments

• max_retries - The maximum number of times to retry an operation.

pub fn delay_for_attempt(&self, attempt: u32) -> Duration

Calculates the delay duration for a specific retry attempt.

The delay is calculated using exponential backoff, and optionally includes jitter.

Arguments

• attempt - The current retry attempt number (starting from 0).

Returns

A Duration to wait before the next attempt.

Trait Implementations

impl Clone for RetryConfig

fn clone(&self) -> RetryConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RetryConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for RetryConfig

fn default() -> Self

Creates a default RetryConfig.

The default settings are:

• max_retries: 3
• base_delay_ms: 1000 (1 second)
• max_delay_ms: 30000 (30 seconds)
• backoff_multiplier: 2.0
• jitter: true
