Struct SpanContext 

pub struct SpanContext {
    pub trace_id: String,
    pub span_id: String,
    pub parent_span_id: Option<String>,
    pub sampled: bool,
    pub start_ms: u64,
}

A span in flight: the trace it belongs to, this hop’s span, its parent, the sampling decision, and when it started (unix millis).

Fields

trace_id: String

32-hex-char trace id, shared across the whole distributed trace.

span_id: String

16-hex-char span id for this gateway hop.

parent_span_id: Option<String>

The caller’s span id, when the request arrived already traced.

sampled: bool

Whether this trace is sampled (exported).

start_ms: u64

Span start time (unix millis).
