Enum RetryPolicy

pub enum RetryPolicy {
    Immediate {
        current_retries: u32,
        max_retries: u32,
    },
    ConstantDelay {
        current_retries: u32,

        delay: Duration,
    },

        max_retries: u32,
        initial_delay: Duration,
        max_delay: Duration,
    },
}

A policy for configuring how requests should retry when they fail.

Variants

Immediate

Retry the request immediately.

Fields

current_retries: u32

The number of retries attempted so far.

max_retries: u32

The maximum number of retries to attempt.

ConstantDelay

Retry the request after a delay.

Fields

current_retries: u32

The number of retries attempted so far.

max_retries: u32

The maximum number of retries to attempt.

delay: Duration

The delay between retries.

ExponentialBackoff

Retry the request after a delay, with exponential backoff.

Fields

current_retries: u32

The number of retries attempted so far.

max_retries: u32

The maximum number of retries to attempt.

initial_delay: Duration

The initial delay between retries.

max_delay: Duration

The maximum delay between retries.

Implementations

impl RetryPolicy

pub fn max_retries(&self) -> u32

pub async fn failed_request(&mut self) -> bool

Executes a retry policy, including incrementing the retry count and delaying if necessary.

pub fn immediate(max_retries: u32) -> Self

Returns a new retry policy that will retry immediately, with a maximum number of retries.

pub fn constant_delay(max_retries: u32, delay: Duration) -> Self

Returns a new retry policy that will retry after a constant delay, with a maximum number of retries.

pub fn exponential_backoff( max_retries: u32, initial_delay: Duration, max_delay: Duration, ) -> Self

Returns a new retry policy that will retry after an exponentially increasing delay, with a maximum number of retries, and a maximum delay.

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 Default for RetryPolicy

fn default() -> Self

Returns the “default value” for a type.
