Enum OperationAction 

#[repr(u8)]
pub enum OperationAction {
    Start = 0,
    Succeed = 1,
    Fail = 2,
    Cancel = 3,
    Retry = 4,
}

Action to perform on an operation during checkpoint.

This enum uses #[repr(u8)] for compact memory representation (1 byte). Explicit discriminant values ensure stability across versions.

Variants

Start = 0

Start a new operation

Succeed = 1

Mark operation as succeeded

Fail = 2

Mark operation as failed

Cancel = 3

Cancel an operation (e.g., cancel a wait) Requirements: 5.5

Retry = 4

Retry an operation with optional payload (state) for wait-for-condition pattern Requirements: 4.7, 4.8, 4.9

Trait Implementations

impl Clone for OperationAction

fn clone(&self) -> OperationAction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OperationAction

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for OperationAction

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for OperationAction

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

Formats the value using the given formatter.

impl PartialEq for OperationAction

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
