Struct RetryConfig 

pub struct RetryConfig {
    pub status_codes: Vec<u16>,
    pub max_retries: usize,
    pub exponential_base: f64,
    pub max_delay: Duration,
    pub initial_delay: Duration,
    pub on_retry: Option<RetryCallback>,
}

Configuration for automatic retry behavior.

By default, retries on 429, 5xx statuses and connection/timeout errors with up to 3 attempts using exponential backoff starting at 1 second.

Fields

status_codes: Vec<u16>

HTTP status codes that trigger a retry.

max_retries: usize

Maximum number of retry attempts (not counting the initial request).

exponential_base: f64

Exponential base for backoff (default: 2.0 → 1s, 2s, 4s, …).

max_delay: Duration

Maximum delay between retries (default: 60s).

initial_delay: Duration

Starting delay before first retry (default: 1s).

on_retry: Option<RetryCallback>

Optional callback invoked before each retry with (attempt, error, delay).

Implementations

impl RetryConfig

pub fn none() -> Self

No retries — useful when you want explicit control.

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

Compute the delay duration for a given retry attempt number (0-based).

pub fn should_retry(&self, error: &LimitlessError) -> bool

Returns true if the error is retryable according to this config.

pub fn with_on_retry<F>(self, callback: F) -> Self

where F: Fn(usize, &LimitlessError, Duration) + Send + Sync + 'static,

Attach a callback that fires before each retry.

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.
