Struct ExponentialBackoff 

pub struct ExponentialBackoff {
    pub base_delay: Duration,
    pub max_delay: Duration,
    pub max_exponent: u32,
}

Exponential backoff: min(base * 2^attempt, max_delay).

Fields

base_delay: Duration

max_delay: Duration

max_exponent: u32

Maximum exponent to prevent overflow (default: 16).

Implementations

impl ExponentialBackoff

pub fn new(base_delay: Duration, max_delay: Duration) -> Self

pub fn default_settings() -> Self

pub fn with_max_exponent(self, max_exponent: u32) -> Self
