Enum RowKind 

#[non_exhaustive]
pub enum RowKind {
    StateEntry,
    CompensationCompletion,
    StepCursor,
}

Why a CheckpointRow was written — distinguishes ordinary state-entry rows from saga compensation-completion rows and SteppedTask cursor rows so resume_from can route each correctly.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

StateEntry

An ordinary “the FSM entered this state” row (the common case).

CompensationCompletion

A saga compensatable task’s completion row, carrying its serialized output in output_blob.

StepCursor

A SteppedTask iteration row, carrying the serialized cursor in output_blob.

Trait Implementations

impl Clone for RowKind

fn clone(&self) -> RowKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for RowKind

impl Debug for RowKind

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

Formats the value using the given formatter.

impl Default for RowKind

fn default() -> RowKind

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for RowKind

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for RowKind

impl PartialEq for RowKind

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
