Struct AttemptOutcome 

#[non_exhaustive]
pub struct AttemptOutcome<'a> {
    pub request: &'a Request,
    pub attempt: u32,
    pub status: Option<StatusCode>,
    pub error: Option<&'a CrawlError>,
    pub anti_bot: Option<AntiBotTech>,
    pub proxy_info: Option<&'a ProxyInfo>,
    pub session_id: Option<&'a SessionId>,
    pub response_bytes: Option<usize>,
}

Borrowed metadata describing a failed request attempt.

session_id, proxy_info, and response_bytes are present when the failed attempt produced a handler context, and absent for fetch-level failures.

Examples

use millipede_core::retry_strategy::AttemptOutcome;

fn is_first_attempt(outcome: &AttemptOutcome<'_>) -> bool {
    outcome.attempt == 0
}

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

request: &'a Request

Request after preparation for this attempt.

attempt: u32

The request’s retry count, independent of session rotations.

status: Option<StatusCode>

Observed or error-carried HTTP status.

error: Option<&'a CrawlError>

Attempt error.

anti_bot: Option<AntiBotTech>

Detected anti-bot technology.

proxy_info: Option<&'a ProxyInfo>

Proxy used by the attempt, when known.

session_id: Option<&'a SessionId>

Session used by the attempt, when known.

response_bytes: Option<usize>

Number of response body bytes, when known.
