Struct opentelemetry::trace::SpanContext

pub struct SpanContext { /* fields omitted */ }

This is supported on crate feature trace only.

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

Implementations

impl SpanContext

pub fn empty_context() -> Self

Create an invalid empty span context

pub fn new(
    trace_id: TraceId,
    span_id: SpanId,
    trace_flags: u8,
    is_remote: bool,
    trace_state: TraceState
) -> Self

Construct a new SpanContext

pub fn trace_id(&self) -> TraceId

A valid trace identifier is a non-zero u128.

pub fn span_id(&self) -> SpanId

A valid span identifier is a non-zero u64.

pub fn trace_flags(&self) -> u8

Returns details about the trace. Unlike TraceState values, these are present in all traces. Currently, the only option is a boolean sampled flag.

pub fn is_valid(&self) -> bool

Returns a bool flag which is true if the SpanContext has a valid (non-zero) trace_id and a valid (non-zero) span_id.

pub fn is_remote(&self) -> bool

Returns true if the SpanContext was propagated from a remote parent.

pub fn is_deferred(&self) -> bool

Returns if the deferred bit is set in the trace flags

pub fn is_debug(&self) -> bool

Returns if the debug bit is set in the trace flags

pub fn is_sampled(&self) -> bool

Returns true if the SpanContext is sampled.

pub fn trace_state(&self) -> &TraceState

Returns the context's TraceState.

Trait Implementations

impl Clone for SpanContext

pub fn clone(&self) -> SpanContext

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SpanContext

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SpanContext

pub fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl PartialEq<SpanContext> for SpanContext

pub fn eq(&self, other: &SpanContext) -> bool

This method tests for self and other values to be equal, and is used by ==.

pub fn ne(&self, other: &SpanContext) -> bool

This method tests for !=.

impl Serialize for SpanContext

pub fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error> where
    __S: Serializer, 

Serialize this value into the given Serde serializer.
