Struct RetryConfig 

pub struct RetryConfig {
    pub max_retries: u32,
    pub base_delay_ms: u64,
    pub max_delay_ms: u64,
    pub retryable_status_codes: Vec<u16>,
}

Configuration for API retry behavior

Fields

max_retries: u32

Maximum number of retry attempts (0 = no retries)

base_delay_ms: u64

Base delay in milliseconds for exponential backoff

max_delay_ms: u64

Maximum delay in milliseconds (cap for exponential growth)

retryable_status_codes: Vec<u16>

HTTP status codes that trigger a retry

Implementations

impl RetryConfig

pub fn disabled() -> Self

Create a retry config with no retries (disabled)

pub fn is_retryable_status(&self, status: StatusCode) -> bool

Check if a given HTTP status code is retryable

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

Calculate the delay for a given attempt number (0-indexed)

Uses exponential backoff: base_delay * 2^attempt, capped at max_delay. Adds jitter of ±25% to avoid thundering herd.

pub fn parse_retry_after(header_value: Option<&str>) -> Option<Duration>

Parse Retry-After header value to get a delay duration.

Supports:

• Integer seconds (e.g., “5”)
• Decimal seconds (e.g., “1.5”)

Returns None if the header is missing or unparseable.

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.

impl<'de> Deserialize<'de> for RetryConfig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for RetryConfig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
