Enum StatusPolicy 

#[non_exhaustive]
pub enum StatusPolicy {
    Classify,
    Accept,
}

How a backend treats error statuses.

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.

Classify

4xx and 5xx responses become errors, so the crawler retries or fails them without a handler having to check:

• 408, 429 and 5xx are retryable Http errors; 429 and 503 honour Retry-After by pausing the request’s host.
• Other 4xx are Rejected errors, which are not retried.

Accept

Every response is returned, whatever its status.

Implementations

impl StatusPolicy

pub fn check<B>(self, response: Response<B>) -> Result<Response<B>>

Applies the policy to a response, returning it unless its status is an error under the policy.

Errors

Returns the error the status maps to, with its final URI and any Retry-After delay.
