Struct SubscriptionRetryPolicy 

pub struct SubscriptionRetryPolicy {
    pub max_retries: u32,
    pub base_delay_ms: u64,
    pub max_delay_ms: u64,
    pub backoff_multiplier: f64,
}

Configuration for subscription query retry behavior

When a subscription query fails during re-execution, it may be automatically retried with exponential backoff if the error is classified as transient.

Fields

max_retries: u32

Maximum number of retry attempts after initial failure

Default: 3 Once retries are exhausted, the subscription enters a failed state and the error is sent to the client.

base_delay_ms: u64

Base delay for the first retry in milliseconds

Default: 1000 (1 second) Used as the starting point for exponential backoff calculation.

max_delay_ms: u64

Maximum delay between retries in milliseconds

Default: 30000 (30 seconds) Exponential backoff is capped at this duration to prevent excessive delays.

backoff_multiplier: f64

Multiplier for exponential backoff

Default: 2.0 Delay for retry N = base_delay * (multiplier ^ N), capped at max_delay

Trait Implementations

impl Clone for SubscriptionRetryPolicy

fn clone(&self) -> SubscriptionRetryPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SubscriptionRetryPolicy

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

Formats the value using the given formatter.

impl Default for SubscriptionRetryPolicy

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for SubscriptionRetryPolicy

fn eq(&self, other: &SubscriptionRetryPolicy) -> 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.
