Enum WorkerPoolError 

pub enum WorkerPoolError {
    QueueFull,
    NoHealthyWorker,
    Worker(WorkerProtocolError),
    Timeout,
    ShuttingDown,
    CircuitOpen,
    InvalidRequest {
        reason: String,
    },
}

Pool-level errors surfaced to runtime callers.

Variants

QueueFull

Worker queue reached configured limit.

NoHealthyWorker

No healthy worker could accept the request.

Worker(WorkerProtocolError)

Worker-side execution failed.

Timeout

Request timed out while waiting for worker completion.

ShuttingDown

Request was cancelled because pool is shutting down.

CircuitOpen

Request rejected by circuit breaker hook.

InvalidRequest

Request violated runtime security policy.

Fields

reason: String

Rejection reason.

Trait Implementations

impl Clone for WorkerPoolError

fn clone(&self) -> WorkerPoolError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WorkerPoolError

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

Formats the value using the given formatter.

impl Display for WorkerPoolError

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

Formats the value using the given formatter.

impl Error for WorkerPoolError

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 WorkerPoolError

fn eq(&self, other: &WorkerPoolError) -> 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.
