StartMeta

fusee_core::record

Struct StartMeta 

pub struct StartMeta<B> {
    pub by: Option<B>,
    pub trace: Option<B>,
}
Expand description

The rare fields of a Start record, boxed so every record stays small.

Fields§

§by: Option<B>

Who asked (audit; see Record), for a reset’s start.

§trace: Option<B>

The W3C traceparent of the request that started the run, when the starter traces: the run’s spans join that trace.

Implementations§

§

impl<B> StartMeta<B>

pub fn of(by: Option<B>, trace: Option<B>) -> Option<Box<Self>>

None when both are absent, so a plain start carries nothing.
