Enum AttemptOutcome 

pub enum AttemptOutcome {
    Ok,
    Error,
    Timeout,
    Cancelled,
    Retry,
}

Terminal attempt outcome label for ff_attempt_outcome_total.

The variant set is fixed at 5 by the Observability RFC prereq #4 adjudication so cardinality stays bounded at 5 × N lanes. Kept feature-agnostic (defined here, not in real/shim) so call sites can construct the value identically whether metrics are compiled in or not.

Variants

Ok

Attempt completed successfully (terminal-ok / complete FCALL).

Error

Attempt failed terminally — no retries left.

Timeout

Attempt failed with classification = Timeout.

Cancelled

Attempt was cancelled (worker or flow-level cancel).

Retry

Attempt failed but a retry was scheduled.

Implementations

impl AttemptOutcome

pub fn as_stable_str(&self) -> &'static str

Stable &'static str label — matches the Prometheus exposition.

Trait Implementations

impl Clone for AttemptOutcome

fn clone(&self) -> AttemptOutcome

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AttemptOutcome

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for AttemptOutcome

fn eq(&self, other: &AttemptOutcome) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
