Enum SafetyLevel 

pub enum SafetyLevel {
    Pure,
    Idempotent,
    Transactional,
}

Classification of a task’s side-effect safety characteristics.

This classification informs the engine about the safety guarantees of a task’s handler, enabling appropriate retry and scheduling decisions.

Variants

Pure

The task produces no side effects. Safe to retry unconditionally.

Idempotent

The task may produce side effects but is safe to retry (applying the same operation multiple times has the same effect as once).

Transactional

The task produces non-idempotent side effects. Retrying may cause duplicate effects. Use with caution.

Trait Implementations

impl Clone for SafetyLevel

fn clone(&self) -> SafetyLevel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SafetyLevel

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

Formats the value using the given formatter.

impl Default for SafetyLevel

fn default() -> SafetyLevel

Returns the “default value” for a type.

impl Hash for SafetyLevel

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SafetyLevel

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