Enum SagaError 

pub enum SagaError {
    CompensationFailed {
        failed_step: usize,
        forward_completed: usize,
        compensate_failed_at: usize,
        forward_responses: Vec<Vec<u8>>,
        source: ClientError,
    },
    Journal(SagaJournalError),
    NotFound,
    CatalogVersionChanged {
        pinned: u32,
        current: u32,
    },
}

Why a saga could not finish cleanly.

Variants

CompensationFailed

A compensate command failed after partial forward progress.

Fields

failed_step: usize

Forward step that failed.

forward_completed: usize

Forward steps that committed before the failure.

compensate_failed_at: usize

Compensate step index that failed.

forward_responses: Vec<Vec<u8>>

Forward responses collected before compensation.

source: ClientError

Client error from the failed compensate RPC.

Journal(SagaJournalError)

Journal persistence failed (saga aborted before mutating client state further).

NotFound

resume_saga found no record for plan.saga_id.

CatalogVersionChanged

Catalog generation changed mid-saga (dynamic catalog expansion).

Fields

pinned: u32

Catalog version pinned when the saga started.

current: u32

Current catalog version observed mid-run.

Trait Implementations

impl Debug for SagaError

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

Formats the value using the given formatter.

impl Display for SagaError

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

Formats the value using the given formatter.

impl Error for SagaError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<SagaJournalError> for SagaError

fn from(source: SagaJournalError) -> Self

Converts to this type from the input type.
