Enum RuntimeErrorKind 

#[non_exhaustive]
pub enum RuntimeErrorKind {
    Closed,
    Poisoned,
    TimedOut,
    CapacityExhausted,
    Unsupported,
    ContextUnavailable,
    Configuration,
    Io,
    Internal,
}

Why a runtime operation failed, for callers that branch on the reason.

RuntimeError::operation names what was attempted; the kind says why it failed. Several kinds share one catalog descriptor: a closed or poisoned owner and a missing runtime context all report runtime.context.unavailable, so only the kind tells them apart.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Closed

The owner, operation, lane or worker no longer admits work: it is shutting down, closed its admission, was cancelled or passed its deadline.

Poisoned

The owning task group was poisoned by a task panic and rejects new work.

TimedOut

A timeout or deadline elapsed while waiting.

CapacityExhausted

A bounded queue, budget or capacity is full.

Unsupported

The request is not supported, for example a schedule whose policy contradicts its configuration.

ContextUnavailable

A required context is missing or in the wrong state, for example no current Tokio runtime.

Configuration

The configuration is invalid or could not be loaded.

Io

An I/O operation failed, including building the Tokio runtime.

Internal

An unexpected internal failure, including a failed task join.
