Enum StepSemantics 

pub enum StepSemantics {
    AtMostOncePerRetry,
    AtLeastOncePerRetry,
}

Execution semantics for step operations.

Variants

AtMostOncePerRetry

Checkpoint before execution - guarantees at most once execution per retry.

AtLeastOncePerRetry

Checkpoint after execution - guarantees at least once execution per retry.

Trait Implementations

impl Clone for StepSemantics

fn clone(&self) -> StepSemantics

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StepSemantics

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

Formats the value using the given formatter.

impl Default for StepSemantics

fn default() -> StepSemantics

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for StepSemantics

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for StepSemantics

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for StepSemantics

impl Eq for StepSemantics

impl StructuralPartialEq for StepSemantics
