Enum TaskletError 

pub enum TaskletError {
    InvalidWorkerCount,
    MemoryEnvelopeInvalid,
    Missing(&'static str),
    Cancelled,
    FuelExhausted,
    Fabric(FabricError),
}

Errors produced by the shared-memory tasklet SDK surface.

These are SDK-side validation errors, distinct from the underlying transport errors in FabricError. A successful submission may still surface a FabricError from the runtime.

Variants

InvalidWorkerCount

max_threads > num_cores, or either is zero.

MemoryEnvelopeInvalid

Memory envelope shared + max_threads * scratch_per_worker overflowed or exceeded the configured tasklet linear-memory budget.

Missing(&'static str)

A required builder field was not set.

Cancelled

The whole tasklet was cancelled (revoke / expiry / explicit cancel).

FuelExhausted

The lease-wide shared fuel pool is exhausted (Phase 48.14 — folds Phase 48.3 follow-up #35). Produced by ?-propagation from CoordinatorCtx::fuel_checkpoint / WorkerCtx::fuel_checkpoint via the From<FuelExhausted> impl below, so programmer source can write ctx.fuel_checkpoint(n)? and propagate a typed fuel error without collapsing it into TaskletError::Cancelled.

Fabric(FabricError)

Underlying transport / host error.

Trait Implementations

impl Clone for TaskletError

fn clone(&self) -> TaskletError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TaskletError

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

Formats the value using the given formatter.

impl From<Cancelled> for TaskletError

fn from(_: Cancelled) -> Self

Converts to this type from the input type.

impl From<FabricError> for TaskletError

fn from(e: FabricError) -> Self

Converts to this type from the input type.

impl From<FuelExhausted> for TaskletError

fn from(_: FuelExhausted) -> Self

Converts to this type from the input type.

impl PartialEq for TaskletError

fn eq(&self, other: &TaskletError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
