Struct RetryPolicy 

pub struct RetryPolicy { /* private fields */ }

How a failed exchange is retried: max_retries extra attempts at most, exponential backoff from base (200 ms, 400 ms, 800 ms, …) clamped to max_delay per wait and max_total across the whole exchange. An upstream-stated Retry-After replaces the computed delay and clamps only to what max_total still allows.

Implementations

impl RetryPolicy

pub fn max_retries(self) -> u32

Extra attempts after the first send.

pub fn base(self) -> Duration

First computed backoff, doubled every attempt.

pub fn max_delay(self) -> Duration

Ceiling on one computed wait. An upstream-stated Retry-After may exceed this; only max_total caps it.

pub fn max_total(self) -> Duration

Ceiling on everything the retries may wait, added up.

pub fn with_max_retries(self, max_retries: u32) -> Self

Sets the retry count.

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

Sets the first computed backoff.

pub fn with_max_delay(self, max_delay: Duration) -> Self

Sets the per-wait ceiling.

pub fn with_max_total(self, max_total: Duration) -> Self

Sets the across-the-exchange ceiling.
