Struct tracing_honeycomb::SpanId

pub struct SpanId { /* fields omitted */ }

Unique Span identifier.

Combines a span's tracing::Id with an instance identifier to avoid id collisions in distributed scenarios.

Display and FromStr are guaranteed to round-trip.

Implementations

impl SpanId

pub fn meta_field_name() -> &'static str
