Struct RetryPolicy 

pub struct RetryPolicy {
    pub retryable: bool,
    pub max_retries: u32,
    pub backoff_strategy: BackoffStrategy,
    pub base_delay: Duration,
    pub max_delay: Duration,
    pub requires_idempotency_key: bool,
}

Deterministic retry behavior for an error

The kernel uses this to decide:

1. Should we retry? (retryable)
2. How many times? (max_retries)
3. How long to wait? (backoff_strategy + base_delay)
4. Is the operation idempotent? (requires_idempotency_key)

Fields

retryable: bool

Whether this error is retryable at all

max_retries: u32

Maximum number of retry attempts (0 = no retries)

backoff_strategy: BackoffStrategy

Backoff strategy for spacing retries

base_delay: Duration

Base delay for backoff calculation

max_delay: Duration

Maximum delay (caps exponential backoff)

requires_idempotency_key: bool

Whether the operation requires an idempotency key for safe retry If true, the kernel MUST generate an IdempotencyKey before retrying

Implementations

impl RetryPolicy

pub fn fatal() -> Self

Create a fatal (non-retryable) policy

pub fn retryable(max_retries: u32) -> Self

Create a simple retryable policy

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

Calculate delay for a given attempt number

pub fn should_retry(&self, attempt: u32) -> bool

Check if a retry should be attempted for the given attempt number

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 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<'de> Deserialize<'de> for RetryPolicy

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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.

impl Serialize for RetryPolicy

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for RetryPolicy
