Enum RetrySchedule 

#[non_exhaustive]
pub enum RetrySchedule {
    Fixed(Duration),
    Exponential {
        min: Duration,
        max: Duration,
    },
}

Schedule for the delay between attempts.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Fixed(Duration)

Fixed delay between every attempt.

Exponential

Exponential backoff: min, min*2, min*4, … capped at max.

Fields

min: Duration

max: Duration

Implementations

impl RetrySchedule

pub fn fixed(d: Duration) -> Self

pub fn exponential(min: Duration, max: Duration) -> Self

pub fn delay_for(self, attempt: u32) -> Duration

Delay before the attemptth retry (0-indexed: attempt 0 is the first retry, i.e. after the initial call has already failed).
