Implementations

impl RetryStrategy

pub fn fixed(delay_secs: u32) -> Self

Create a fixed delay retry strategy

pub fn exponential(base_delay_secs: u32, max_delay_secs: u32) -> Self

Create an exponential backoff retry strategy

pub fn linear( initial_delay_secs: u32, increment_secs: u32, max_delay_secs: u32, ) -> Self

Create a linear backoff retry strategy

pub fn custom(delays: Vec<u32>) -> Self

Create a custom retry strategy with specific delays

pub fn calculate_delay(&self, retry_count: u32) -> Option<Duration>

Calculate the delay for a specific retry attempt

pub fn next_eta(&self, retry_count: u32) -> Option<DateTime<Utc>>

Get the ETA for the next retry

Trait Implementations

impl Clone for RetryStrategy

fn clone(&self) -> RetryStrategy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RetryStrategy

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

Formats the value using the given formatter.

impl Default for RetryStrategy

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for RetryStrategy

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for RetryStrategy

fn eq(&self, other: &RetryStrategy) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for RetryStrategy

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
