CappedExponentialBackoff

Struct CappedExponentialBackoff 

Source
pub struct CappedExponentialBackoff {
    pub max_times: Option<usize>,
    pub base_duration: Duration,
    pub max_interval: Duration,
}
Expand description

自定义的指数退避重试策略,支持最大间隔限制

重试间隔按照指数增长,但不会超过 max_interval

  • 第 1 次重试:base_duration × 2^0
  • 第 2 次重试:base_duration × 2^1
  • 第 n 次重试:min(base_duration × 2^(n-1), max_interval)

Fields§

§max_times: Option<usize>

最大重试次数,None 表示无限制

§base_duration: Duration

基础延迟时间(第一次重试前的等待时间)

§max_interval: Duration

最大延迟间隔(重试间隔不会超过这个值)

Implementations§

impl CappedExponentialBackoff

Source

pub fn new( max_times: Option<usize>, base_duration: Duration, max_interval: Duration, ) -> Self

创建一个新的带上限的指数退避策略

§Arguments
  • max_times - 最大重试次数,None 表示无限制
