Struct TaskRetryPolicy 

pub struct TaskRetryPolicy {
    pub max: u32,
    pub delay: Option<String>,
    pub backoff: Option<TaskRetryBackoff>,
    pub when: Option<Vec<String>>,
}

Retry policy for individual tasks — transparent retries on failure, independent of try/catch retry mechanisms.

Unlike catch.retry which wraps an entire try block and exposes errors to catch logic, TaskRetryPolicy performs transparent retries: if the task succeeds within the retry limit, the failure is invisible to the workflow.

Fields

max: u32

Maximum number of retry attempts

delay: Option<String>

Delay between retries. Supports ISO 8601 duration strings (e.g., “PT1S”, “PT5M”) or runtime expressions (e.g., “${ .retryDelay }”)

backoff: Option<TaskRetryBackoff>

Backoff strategy: “fixed” (default), “linear”, or “exponential”

when: Option<Vec<String>>

Conditions under which to retry. Matches against error kind (e.g., “communication”, “timeout”) or HTTP status patterns (e.g., “5xx”, “429”). If empty, retries on all errors.

Trait Implementations

impl Clone for TaskRetryPolicy

fn clone(&self) -> TaskRetryPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TaskRetryPolicy

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

Formats the value using the given formatter.

impl Default for TaskRetryPolicy

fn default() -> TaskRetryPolicy

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TaskRetryPolicy

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TaskRetryPolicy

fn eq(&self, other: &TaskRetryPolicy) -> 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 TaskRetryPolicy

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
