Maximum number of attempts (including initial attempt)

base_delay: Duration

Base delay for backoff

max_delay: Duration

Maximum delay between retries

strategy: BackoffStrategy

Implementations

impl RetryPolicy

pub fn exponential(base_delay: Duration, max_attempts: u32) -> Self

Create a new retry policy with exponential backoff

Arguments

• base_delay - Initial delay between retries
• max_attempts - Maximum number of attempts

pub fn fixed(delay: Duration, max_attempts: u32) -> Self

Create a retry policy with fixed delays

pub fn linear(base_delay: Duration, max_attempts: u32) -> Self

Create a retry policy with linear backoff

pub fn with_max_delay(self, max_delay: Duration) -> Self

Set maximum delay

pub fn with_jitter(self, jitter: JitterType) -> Self

Set jitter type

pub fn with_timeout(self, timeout: Duration) -> Self

Set total timeout

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

Set backoff multiplier

pub async fn retry<F, Fut, T, E>(&self, f: F) -> Result<T>

where F: FnMut() -> Fut, Fut: Future<Output = Result<T, E>>, E: Error + Send + Sync + 'static,

Execute a function with retry logic

Arguments

• f - Function to retry

Returns

Result of the function or last error

Trait Implementations

impl Clone for RetryPolicy

fn clone(&self) -> RetryPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RetryPolicy

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

Formats the value using the given formatter.

impl Default for RetryPolicy

fn default() -> Self

impl<'de> Deserialize<'de> for RetryPolicy

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for RetryPolicy

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
