Struct BoxedSpan

pub struct BoxedSpan(/* private fields */);

Available on crate feature trace only.

Wraps the BoxedTracer’s Span so it can be used generically by applications without knowing the underlying type.

Trait Implementations

impl Debug for BoxedSpan

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Span for BoxedSpan

fn add_event_with_timestamp<T>( &mut self, name: T, timestamp: SystemTime, attributes: Vec<KeyValue>, )

where T: Into<Cow<'static, str>>,

Records events at a specific time in the context of a given Span.

Note that the OpenTelemetry project documents certain “standard event names and keys” which have prescribed semantic meanings.

fn span_context(&self) -> &SpanContext

Returns the SpanContext for the given Span.

Adds a link to this span

fn end_with_timestamp(&mut self, timestamp: SystemTime)

Finishes the span with given timestamp.

fn add_event<T>(&mut self, name: T, attributes: Vec<KeyValue>)

where T: Into<Cow<'static, str>>,
