Struct Event 

pub struct Event {
    pub kind: &'static str,
    pub at: SystemTime,
    pub duration: Option<Duration>,
    pub fields: BTreeMap<String, Json>,
}

One recorded moment: a request, a query, a dispatched job, an exception.

Fields

kind: &'static str

A dotted, stable identifier: http.request, db.query, ai.call.

at: SystemTime

duration: Option<Duration>

How long the recorded work took, when it was a span rather than a point.

fields: BTreeMap<String, Json>
