Struct RetryPolicy 

pub struct RetryPolicy {
    pub max_attempts: u32,
    pub initial_backoff: Duration,
    pub max_backoff: Duration,
    pub multiplier: f64,
}

Retry policy: exponential backoff with a maximum number of attempts. Defaults match the Go reference driver: 3 attempts, 1s initial backoff, 30s max backoff, multiplier 2.0. No jitter.

Fields

max_attempts: u32

Maximum number of attempts, including the first call. Values < 1 are treated as 1.

initial_backoff: Duration

Backoff before the first retry.

max_backoff: Duration

Maximum backoff (clamp ceiling).

multiplier: f64

Exponential multiplier per attempt.

Implementations

impl RetryPolicy

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

Compute the backoff for a 1-indexed attempt: initial_backoff * multiplier^(attempt-1), clamped to max_backoff.

Trait Implementations

impl Clone for RetryPolicy

fn clone(&self) -> RetryPolicy

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for RetryPolicy

impl Debug for RetryPolicy

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for RetryPolicy

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for RetryPolicy

fn eq(&self, other: &RetryPolicy) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
