Struct RetryPolicy 

pub struct RetryPolicy {
    pub max_retries: u32,
    pub initial_backoff: Duration,
    pub max_backoff: Duration,
    pub backoff_multiplier: f64,
    pub jitter: bool,
}

Retry policy for transient error handling.

Per ADR-009, the driver can automatically retry operations that fail with transient errors (deadlocks, Azure service busy, etc.).

Fields

max_retries: u32

Maximum number of retry attempts (default: 3).

initial_backoff: Duration

Initial backoff duration before first retry (default: 100ms).

max_backoff: Duration

Maximum backoff duration between retries (default: 30s).

backoff_multiplier: f64

Multiplier for exponential backoff (default: 2.0).

jitter: bool

Whether to add random jitter to backoff times (default: true).

Implementations

impl RetryPolicy

pub fn new() -> Self

Create a new retry policy with defaults.

pub fn max_retries(self, max: u32) -> Self

Set the maximum number of retry attempts.

pub fn initial_backoff(self, backoff: Duration) -> Self

Set the initial backoff duration.

pub fn max_backoff(self, backoff: Duration) -> Self

Set the maximum backoff duration.

pub fn backoff_multiplier(self, multiplier: f64) -> Self

Set the backoff multiplier for exponential backoff.

pub fn jitter(self, enabled: bool) -> Self

Enable or disable jitter.

pub fn no_retry() -> Self

Disable automatic retries.

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

Calculate the backoff duration for a given retry attempt.

Uses exponential backoff with optional jitter.

pub fn should_retry(&self, attempt: u32) -> bool

Check if more retries are allowed for the given attempt number.
