Enum StepError 

pub enum StepError {
    PropagatorFailed {
        name: String,
        reason: PropagatorError,
    },
    AllocationFailed,
    TickRollback,
    TickDisabled,
    DtOutOfRange,
    ShuttingDown,
}

Errors from the tick engine during step().

Corresponds to the TickEngine and Pipeline subsystem codes in HLD §9.7.

Variants

PropagatorFailed

A propagator returned an error during execution (MURK_ERROR_PROPAGATOR_FAILED).

Fields

name: String

Name of the failing propagator.

reason: PropagatorError

The underlying propagator error.

AllocationFailed

Arena allocation failed — OOM during generation staging (MURK_ERROR_ALLOCATION_FAILED).

TickRollback

The tick was rolled back due to a propagator failure (MURK_ERROR_TICK_ROLLBACK).

TickDisabled

Ticking is disabled after consecutive rollbacks (MURK_ERROR_TICK_DISABLED, Decision J).

DtOutOfRange

The requested dt exceeds a propagator’s max_dt constraint (MURK_ERROR_DT_OUT_OF_RANGE).

ShuttingDown

The world is shutting down (MURK_ERROR_SHUTTING_DOWN, Decision E).

Trait Implementations

impl Clone for StepError

fn clone(&self) -> StepError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StepError

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

Formats the value using the given formatter.

impl Display for StepError

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

Formats the value using the given formatter.

impl Error for StepError

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.
