Enum WorkflowWorkerError 

#[non_exhaustive]
pub enum WorkflowWorkerError {
    InvalidConfig(String),
    DuplicateDefinition {
        workflow: String,
        version: u32,
    },
    Store(WorkflowStoreError),
    Checkpoint(CheckpointError),
    Budget(BudgetExceeded),
}

Worker construction or execution failure.

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.

InvalidConfig(String)

The worker configuration violates a timing invariant.

DuplicateDefinition

A definition identity is already registered.

Fields

workflow: String

Stable workflow name.

version: u32

Stable workflow version.

Store(WorkflowStoreError)

Distributed task-control persistence failed.

Checkpoint(CheckpointError)

Checkpoint persistence or decoding failed.

Budget(BudgetExceeded)

Persisted usage exceeds the registered workflow budget.

Trait Implementations

impl Debug for WorkflowWorkerError

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

Formats the value using the given formatter.

impl Display for WorkflowWorkerError

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

Formats the value using the given formatter.

impl Error for WorkflowWorkerError

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.
