Observed

Struct Observed 

Source
pub struct Observed<'a> {
    pub subject: &'a Subject<'a>,
    pub policy: PolicyId,
    pub compiled: CompiledId,
    pub outcome: &'a Outcome,
}
Expand description

One evaluator’s account of a single policy’s attempt and outcome, on its declared observation surface.

The decision channel (Evaluator::evaluate) short-circuits once an overall verdict cannot get any more severe. This one does not: a metapolicy that freezes agents for repeatedly tripping other policies has to see every attempt and outcome on its declared surface, whether or not evaluation of the write as a whole stopped early.

Fields§

§subject: &'a Subject<'a>

The subject the attempt was against.

§policy: PolicyId

Which policy this attempt and outcome belong to, in this crate’s own bookkeeping – useful for a caller correlating this event with a crate::evaluate::Verdict, but not what an evaluator serving many compiled policies uses to tell them apart; see compiled.

§compiled: CompiledId

Which compiled artifact this attempt and outcome belong to, in the evaluator’s own naming – see CompiledId’s doc comment. This, not policy, is what a multi-policy evaluator consults.

§outcome: &'a Outcome

The verdict every policy that judged the subject reached together: what the write path did with the attempt, not only what this policy said.
