Struct Span

pub struct Span<Visitor, SpanId, TraceId> {
    pub id: SpanId,
    pub trace_id: TraceId,
    pub parent_id: Option<SpanId>,
    pub initialized_at: SystemTime,
    pub completed_at: SystemTime,

}

A Span holds ready-to-publish information gathered during the lifetime of a tracing::Span.

Fields

id: SpanId

id identifying this span

trace_id: TraceId

TraceId identifying the trace to which this span belongs

parent_id: Option<SpanId>

optional parent span id

initialized_at: SystemTime

UTC time at which this span was initialized

completed_at: SystemTime

chrono::Duration elapsed between the time this span was initialized and the time it was completed

meta: &'static Metadata<'static>

tracing::Metadata for this span

service_name: &'static str

name of the service on which this span occured

values: Visitor

values accumulated by visiting fields observed by the tracing::Span this span was derived from
