Enum JudgmentError 

pub enum JudgmentError {
    Invalid(String),
    Unauthorized,
    Exhausted,
    RateLimited {
        retry_after: Option<Duration>,
    },
    Unavailable {
        status: u16,
    },
    Transport(Box<dyn Error + Send + Sync + 'static>),
    Malformed(String),
}

The failure classes a judgment backend reports.

The classes are stable across backends so a decision site can fail closed the same way whichever backend answers. No variant carries a request body, a response body, or a credential.

Variants

Invalid(String)

The backend rejected the request shape. Retrying the same request cannot succeed.

Unauthorized

The backend refused the credential.

Exhausted

The backend refused for lack of credit or quota.

RateLimited

The backend asked the caller to back off.

Fields

retry_after: Option<Duration>

The backoff the backend suggested, when it sent one.

Unavailable

The backend is temporarily unavailable.

Fields

status: u16

The HTTP status the backend answered with.

Transport(Box<dyn Error + Send + Sync + 'static>)

The request did not complete on the transport.

Malformed(String)

The response did not decode into the answer types.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()
