Expand description
SpanBuilder
allows span attributes to be configured before the span
has started.
use opentelemetry::{
global,
trace::{TracerProvider, SpanBuilder, SpanKind, Tracer},
};
let tracer = global::tracer("example-tracer");
// The builder can be used to create a span directly with the tracer
let _span = tracer.build(SpanBuilder {
name: "example-span-name".into(),
span_kind: Some(SpanKind::Server),
..Default::default()
});
// Or used with builder pattern
let _span = tracer
.span_builder("example-span-name")
.with_kind(SpanKind::Server)
.start(&tracer);
Fields§
§trace_id: Option<TraceId>
Trace id, useful for integrations with external tracing systems.
span_id: Option<SpanId>
Span id, useful for integrations with external tracing systems.
span_kind: Option<SpanKind>
Span kind
name: Cow<'static, str>
Span name
start_time: Option<SystemTime>
Span start time
end_time: Option<SystemTime>
Span end time
attributes: Option<Vec<KeyValue>>
Span attributes that are provided at the span creation time. More attributes can be added afterwards. Providing duplicate keys will result in multiple attributes with the same key, as there is no de-duplication performed.
events: Option<Vec<Event>>
Span events
links: Option<Vec<Link>>
Span Links
status: Status
Span status
sampling_result: Option<SamplingResult>
Sampling result
