}

Errors that can occur during executor operations.

Variants

ShuttingDown

Executor is shutting down

AlreadyRunning

Executor is already running

InvalidConfiguration

Executor configuration is invalid

InvalidLocalQueueInitialCapacity

The requested local queue initial capacity cannot form a supported allocation.

Fields

requested: usize

Requested slot count before power-of-two normalization.

ThreadPoolCreationFailed

Thread pool creation failed

SpawnFailed(TaskError)

Task spawn failed

ResourceExhausted(String)

Resource exhaustion detected

PerformanceAnomaly(String)

Performance anomaly detected

NoSchedulerAvailable

No scheduler available

SchedulerError(SchedulerError)

Scheduler error

WorkerPlacementFailed

A worker could not be confined to its planned logical processor.

Reported by construction under WorkerPlacement::Pinned. When several workers fail, the lowest-numbered one is named. The scheduler was not started: no worker outlives the failed construction.

Fields

worker: usize

Index of the worker whose binding failed.

processor: u32

Flattened logical processor id the worker was planned onto.

cause: PlacementFailure

Why the binding did not take effect.

Trait Implementations

impl Clone for ExecutorError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExecutorError

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

Formats the value using the given formatter.

impl Display for ExecutorError

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

Formats the value using the given formatter.

impl Eq for ExecutorError

impl Error for ExecutorError

Available on crate feature std only.

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 PartialEq for ExecutorError

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

Equality operator ==.

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

Inequality operator !=.
