enum TopicErrorKind

Why a topic operation failed.

Example:

oxl✓ checked in CI

fn describe(k: TopicErrorKind) -> str {
  match k {
    .Unavailable => "nothing was stored, retry"
    .Unknown => "may or may not be stored"
    .AccessDenied => "policy refused"
    .Decode => "element has a different type"
    .Other => "other"
  }
}

fn main() io {
  print(describe(TopicErrorKind.Unknown))
}

Output

may or may not be stored

pub(api) enum TopicErrorKind

Since. 1.0.0-beta

Variants

`Unavailable`	The store was not reachable or has no leader right now (nothing was stored).
`Unknown`	The outcome is unknown: the element may or may not have been stored (publish again to be sure of at-least-once).
`AccessDenied`	The policy of the topic refuses the caller.
`Decode`	A stored element does not decode as the topic's type.
`Other`	Any other failure.
