Enum ClassifierError 

pub enum ClassifierError {
    NotConfigured,
    Rejected(String),
    Transient {
        retry_after: Option<Duration>,
    },
    Transport(String),
}

Classification failures.

NotConfigured sits on the error enum here, unlike SendOutcome::NotConfigured and PushOutcome::NotConfigured: a decision has no “delivered but not configured” middle state, so an unwired port is an error the caller matches, not an outcome it inspects.

Transient deliberately carries only retry_after, where PushError::Transient also carries a message: with no provider text of its own there is nothing to scrub, and provider text belongs on Rejected and Transport.

The two variants that carry provider text are sanitized in Display, the same way TextModelError’s, PushError’s and MailError’s are (issue #235). What an adapter wraps is the provider’s own words, and state is exactly the kind of value that rides back in them — a triage module sends a customer’s note, and the provider’s 4xx quotes it straight back. Display therefore runs it through crate::logging::scrub_text; Debug still shows the raw string for tests.

Variants

NotConfigured

The port has no adapter — the venture did not wire it. Nothing is wrong with the questions: a module may degrade, the way it degrades on a NotConfigured mailer or text model.

Rejected(String)

The provider refused the request (a 4xx), or the adapter refused the question set — validate_questions exists so that a malformed set lands here and never on a panic. Not retryable without a change.

Transient

A transient failure (a 5xx, a 429, a transport error): retry later, and not before retry_after when the provider named one. Carries no message — provider text belongs on Rejected and Transport.

Fields

retry_after: Option<Duration>

Transport(String)

The request never completed as a decision — the adapter could not reach the provider, or the answer did not survive the hop.

Implementations

impl ClassifierError

pub fn retry_after(&self) -> Option<Duration>

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
