Struct Observation 

pub struct Observation {
    pub seq: u64,
    pub subject: Subject,
    pub stage: Stage,
    pub emitter: Emitter,
    pub action: Action,
    pub at: Option<Duration>,
}

One observed fact.

Fields

seq: u64

Sink-assigned sequence position in observation order.

subject: Subject

What the fact is about.

stage: Stage

Where in the pipeline it was seen.

emitter: Emitter

Who owns the decision or the observation.

action: Action

The fact.

at: Option<Duration>

When, as a host-owned monotonic elapsed duration; a measurement, never a semantic field. None when the sink has no Clock.

Implementations

impl Observation

pub fn new( subject: Subject, stage: Stage, emitter: Emitter, action: Action, ) -> Self

A fact with no sequence yet; the sink assigns one.

Trait Implementations
