Enum FeedErrorKind 

#[non_exhaustive]
pub enum FeedErrorKind {
    Gone,
    Refused,
    Retryable,
    Fatal,
}

How a caller must react to a FeedError.

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.

Gone

The receipt no longer names a delivery the caller holds: the unit was acknowledged, failed, or delivered again under a new receipt. The call changed nothing. The caller lets go of that delivery and does not retry.

Refused

The feed refused the request, and sending it again fails the same way: a unit the feed cannot store, such as one over its size limit.

Retryable

Transient: the backend could not take the request now. Retrying may succeed.

Fatal

Unrecoverable: misconfiguration, missing permissions, a feed that no longer exists. The pipeline must stop.
