Struct RetryMiddleware 

pub struct RetryMiddleware {
    pub max_retries: u32,
    pub retry_http_codes: Vec<u16>,
    pub backoff_factor: f64,
    pub max_delay: Duration,
}

Middleware that retries failed requests.

Fields

max_retries: u32

Maximum number of times to retry a request.

retry_http_codes: Vec<u16>

HTTP status codes that should trigger a retry.

backoff_factor: f64

Factor for exponential backoff (delay = backoff_factor * (2^retries)).

max_delay: Duration

Maximum delay between retries.

Implementations

pub fn backoff_factor(self, backoff_factor: f64) -> RetryMiddleware

Sets the factor for exponential backoff.

pub fn max_delay(self, max_delay: Duration) -> RetryMiddleware

Sets the maximum delay between retries.
