Enum ErrorKind 

pub enum ErrorKind {
    Cancelled,
    Recoverable,
    Configuration,
    Fatal,
}

Classification of an Error. Callers branch on .kind() for retry / abort / reconfigure decisions without pattern-matching every variant.

Variants

Cancelled

A deliberate, caller-initiated cancellation (an interrupt-token abort of a blocking read, a dropped wait future, an SDK job abort). Not a failure: the operation stopped because it was asked to. Callers void it — no retry, no error state, no error-level logging; whatever superseded the cancelled work carries on.

Recoverable

Safe to retry or ignore — typically a transient resource shortage.

Configuration

Caller supplied something the backend cannot do. Fix the config and retry; same input will fail the same way.

Fatal

Backend is in an unrecoverable state. Abort the pipeline.
