Struct TaskMetadata 

pub struct TaskMetadata {
    pub display_name: Option<String>,
    pub description: Option<String>,
    pub timeout: Option<Duration>,
    pub retries: Option<RetryPolicy>,
    pub tags: Vec<String>,
    pub version: Option<String>,
    pub priority: Option<Priority>,
}

Metadata associated with a task definition.

This provides optional configuration for task execution behavior, including display information, timeouts, and retry policies.

Fields

display_name: Option<String>

Human-readable name for the task (for UI/logging).

description: Option<String>

Description of what the task does.

timeout: Option<Duration>

Maximum time the task is allowed to run.

retries: Option<RetryPolicy>

Retry policy for failed task executions.

tags: Vec<String>

Tags for categorization and filtering.

version: Option<String>

Schema version string. Included in the definition hash so that bumping this value forces a new workflow version, preventing in-flight workflows from deserializing stale cached results.

priority: Option<Priority>

Execution priority (1 = Critical … 5 = Minimal). None defaults to Normal (3).

Implementations

impl TaskMetadata

pub fn from_node_fields( timeout: Option<Duration>, retries: Option<RetryPolicy>, version: Option<String>, priority: Option<u8>, tags: Vec<String>, ) -> Self

Build a TaskMetadata from the subset of fields actually stored on a WorkflowContinuation::Task node (or in the TaskIndex). display_name and description aren’t stored on continuation nodes, so they default.

Shared by both WorkflowContinuation::build_task_metadata and TaskIndex::build_task_metadata so adding a new continuation-node field only requires updating one place.

Trait Implementations

impl Clone for TaskMetadata

fn clone(&self) -> TaskMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TaskMetadata

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

Formats the value using the given formatter.

impl Default for TaskMetadata

fn default() -> TaskMetadata

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TaskMetadata

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for TaskMetadata

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
