Struct RetryConfig 

pub struct RetryConfig {
    pub initial_delay: Duration,
    pub max_delay: Duration,
    pub factor: f64,
    pub max_retries: Option<usize>,
}

Configuration for connection/operation retry behavior.

Use the preset constructors for common patterns:

• RetryConfig::startup() - Fast-fail for initial connections
• RetryConfig::daemon() - Infinite retry for runtime reconnection
• RetryConfig::query() - Quick retry for individual operations

Fields

initial_delay: Duration

max_delay: Duration

factor: f64

max_retries: Option<usize>

Implementations

impl RetryConfig

pub fn startup() -> Self

Fast-fail retry for initial startup connection. Attempts 5 times with exponential backoff, failing after ~5 seconds. Use this during daemon startup to detect configuration errors quickly.

pub fn daemon() -> Self

Infinite retry for long-running daemon (never give up!). Retries forever with exponential backoff capped at 5 minutes. Use this for runtime reconnection after initial startup succeeds.

pub fn query() -> Self

Quick retry for individual queries (don’t block forever). 3 attempts with fast backoff - if it fails, let caller handle it.

pub fn batch_write() -> Self

Retry config for batch writes (SQL/Redis).

More aggressive than query() to handle transient deadlocks (MySQL 1213) and connection contention under high concurrency. 5 attempts with randomized initial delay to reduce thundering herd.

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

Returns the “default value” for a type.
