Struct CheckpointedResult 

pub struct CheckpointedResult { /* private fields */ }

Result of checking for a checkpointed operation.

This struct provides methods to query the status of a previously checkpointed operation during replay.

Implementations

impl CheckpointedResult

pub fn new(operation: Option<Operation>) -> Self

Creates a new CheckpointedResult with the given operation.

pub fn empty() -> Self

Creates an empty CheckpointedResult (no checkpoint exists).

pub fn is_existent(&self) -> bool

Returns true if a checkpoint exists for this operation.

pub fn is_succeeded(&self) -> bool

Returns true if the operation succeeded.

pub fn is_failed(&self) -> bool

Returns true if the operation failed.

pub fn is_cancelled(&self) -> bool

Returns true if the operation was cancelled.

pub fn is_timed_out(&self) -> bool

Returns true if the operation timed out.

pub fn is_stopped(&self) -> bool

Returns true if the operation was stopped.

pub fn is_pending(&self) -> bool

Returns true if the operation is pending (waiting for retry). Requirements: 3.7, 4.7

pub fn is_ready(&self) -> bool

Returns true if the operation is ready to resume execution. Requirements: 3.7

pub fn is_terminal(&self) -> bool

Returns true if the operation is in a terminal state (completed).

pub fn status(&self) -> Option<OperationStatus>

Returns the operation status if the checkpoint exists.

pub fn operation_type(&self) -> Option<OperationType>

Returns the operation type if the checkpoint exists.

pub fn result(&self) -> Option<&str>

Returns the serialized result if the operation succeeded. This checks both type-specific details (e.g., StepDetails.Result) and the legacy Result field.

pub fn error(&self) -> Option<&ErrorObject>

Returns the error if the operation failed.

pub fn operation(&self) -> Option<&Operation>

Returns a reference to the underlying operation.

pub fn into_operation(self) -> Option<Operation>

Consumes self and returns the underlying operation.

pub fn retry_payload(&self) -> Option<&str>

Returns the retry payload if this is a STEP operation with a payload.

This is used for the wait-for-condition pattern where state is passed between retry attempts via the Payload field.

Returns

The payload string if available, None otherwise.

pub fn attempt(&self) -> Option<u32>

Returns the current attempt number for STEP operations.

Returns

The attempt number (0-indexed) if available, None otherwise.

pub fn callback_id(&self) -> Option<String>

Returns the callback ID for CALLBACK operations.

The callback ID is generated by the Lambda service when a CALLBACK operation is checkpointed and is stored in CallbackDetails.CallbackId.

Returns

The callback ID if this is a CALLBACK operation with a callback ID, None otherwise.

Trait Implementations

impl Clone for CheckpointedResult

fn clone(&self) -> CheckpointedResult

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CheckpointedResult

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

Formats the value using the given formatter.
