Enum RuntimeError 

pub enum RuntimeError {
    Workflow(WorkflowError),
    Backend(BackendError),
    Task(BoxError),
    Join(JoinError),
}

Typed error for the sayiir runtime layer.

Replaces BoxError in internal runtime APIs, keeping BoxError only at true user boundaries (codec traits, user task callbacks).

Variants

Workflow(WorkflowError)

Workflow logic error (cancellation, definition mismatch, task not found, etc.)

Backend(BackendError)

Persistent backend error (storage failures).

Task(BoxError)

User task execution or codec error (opaque — from user-provided code).

Join(JoinError)

Tokio task join error (branch spawn failures).

Implementations

impl RuntimeError

pub fn is_timeout(&self) -> bool

Returns true if this error is a TaskTimedOut workflow error.

Trait Implementations

impl Debug for RuntimeError

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

Formats the value using the given formatter.

impl Display for RuntimeError

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

Formats the value using the given formatter.

impl Error for RuntimeError

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.
