Struct aws_smithy_client::retry::Config

pub struct Config { /* private fields */ }

Retry Policy Configuration

Without specific use cases, users should generally rely on the default values set by [Config::default](Config::default).`

Currently these fields are private and no setters provided. As needed, this configuration will become user-modifiable in the future..

Implementations

impl Config

pub fn with_base(self, base: fn() -> f64) -> Self

Override b in the exponential backoff computation

By default, base is a randomly generated value between 0 and 1. In tests, it can be helpful to override this:

use aws_smithy_client::retry::Config;
let conf = Config::default().with_base(||1_f64);

pub fn with_max_attempts(self, max_attempts: u32) -> Self

Override the maximum number of attempts

max_attempts must be set to a value of at least 1 (indicating that retries are disabled).

pub fn with_initial_backoff(self, initial_backoff: Duration) -> Self

Override the default backoff multiplier of 1 second.

Example

For a request that gets retried 3 times, when initial_backoff is 1 second:

• the first retry will occur after 0 to 1 seconds
• the second retry will occur after 0 to 2 seconds
• the third retry will occur after 0 to 4 seconds

For a request that gets retried 3 times, when initial_backoff is 30 milliseconds:

• the first retry will occur after 0 to 30 milliseconds
• the second retry will occur after 0 to 60 milliseconds
• the third retry will occur after 0 to 120 milliseconds
