Struct rama::telemetry::opentelemetry::trace::SpanContext

pub struct SpanContext { /* private fields */ }
Expand description

Immutable portion of a Span which can be serialized and propagated.

This representation conforms to the W3C TraceContext specification.

Spans that do not have the sampled flag set in their TraceFlags will be ignored by most tracing tools.

Implementations§

§

impl SpanContext

pub const NONE: SpanContext = _

An invalid span context

pub fn empty_context() -> SpanContext

Create an invalid empty span context

pub fn new( trace_id: TraceId, span_id: SpanId, trace_flags: TraceFlags, is_remote: bool, trace_state: TraceState, ) -> SpanContext

Construct a new SpanContext

pub fn trace_id(&self) -> TraceId

The TraceId for this span context.

pub fn span_id(&self) -> SpanId

The SpanId for this span context.

pub fn trace_flags(&self) -> TraceFlags

Returns details about the trace.

Unlike TraceState values, these are present in all traces. The current version of the specification only supports a single flag TraceFlags::SAMPLED.

pub fn is_valid(&self) -> bool

Returns true if the span context has a valid (non-zero) trace_id and a valid (non-zero) span_id.

pub fn is_remote(&self) -> bool

Returns true if the span context was propagated from a remote parent.

pub fn is_sampled(&self) -> bool

Returns true if the sampled trace flag is set.

Spans that are not sampled will be ignored by most tracing tools.

pub fn trace_state(&self) -> &TraceState

A reference to the span context’s TraceState.
