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.

fn is_recording(&self) -> bool

Returns true if this Span is recording information like events with the add_event operation, attributes using set_attributes, status with set_status, etc.

fn set_attribute(&mut self, attribute: KeyValue)

Sets a single Attribute where the attribute properties are passed as arguments.

Note that the OpenTelemetry project documents certain “standard attributes” that have prescribed semantic meanings.

fn set_status(&mut self, code: StatusCode, message: String)

Sets the status of the Span. If used, this will override the default Span status, which is Unset.

fn update_name<T>(&mut self, new_name: T)

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

Updates the Span’s name.

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>>,

An API to record events in the context of a given Span.

fn record_exception(&mut self, err: &dyn Error)

Convenience method to record an exception/error as an Event

fn record_exception_with_stacktrace<T>( &mut self, err: &dyn Error, stacktrace: T, )

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

Convenience method to record a exception/error as an Event with custom stacktrace

fn end(&mut self)

Finishes the Span.
