Gitility.Error exception (Gitility v0.2.0)

Copy Markdown View Source

The normalized error type for every Gitility operation.

Normal failures return {:error, %Gitility.Error{}} — the public API does not raise for repository data, missing objects, timeouts, or backend failures. Callers branch on code and retryable; backend-specific reasons appear only in a sanitized cause.

The struct is also an exception, so !-variants and truly exceptional paths can raise it directly.

provider_timeout          provider_protocol_error  backend_error
runtime_mismatch          internal_error

Two timeouts are deliberately distinct: :await_timeout means Gitility.Job.await/2 gave up waiting but the job is still running; :timeout means the job's own budget expired and the work was cancelled.

Builds an error. Used pervasively inside Gitility; also handy in backend implementations that want to surface normalized errors.
