Struct SpanContext

pub struct SpanContext {
    pub trace_id: TraceId,
    pub span_id: SpanId,
}

A struct representing the context of a span, including its TraceId and SpanId.

Fields

trace_id: TraceId

The trace ID this span belongs to

span_id: SpanId

The unique ID of this span

Implementations

impl SpanContext

pub fn new(trace_id: TraceId, span_id: SpanId) -> SpanContext

Creates a new SpanContext with the given TraceId and SpanId.

Examples

use veecle_telemetry::id::*;

let span_context = SpanContext::new(TraceId(12), SpanId(13));

pub fn generate() -> SpanContext

Creates a new SpanContext with a TraceId generated with the state in the collector.

Returns 0 if the collector has not been initialized via crate::collector::set_exporter.

Examples

use veecle_telemetry::*;

let random = SpanContext::generate();

pub fn from_span(span: &Span) -> Option<SpanContext>

Creates a SpanContext from the given Span. If the Span is a noop span, this function will return None.

Examples

use veecle_telemetry::*;

let span = Span::root("root", SpanContext::generate(), &[]);
let span_context = SpanContext::from_span(&span);

pub fn current() -> Option<SpanContext>

Creates a SpanContext from the current local parent span. If there is no local parent span, this function will return None.

Examples

use veecle_telemetry::*;

let span = Span::root("root", SpanContext::generate(), &[]);
let _guard = span.entered();

let span_context = SpanContext::current();

Trait Implementations

impl Clone for SpanContext

fn clone(&self) -> SpanContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SpanContext

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

Formats the value using the given formatter.

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

fn deserialize<__D>( __deserializer: __D, ) -> Result<SpanContext, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for SpanContext

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for SpanContext

fn cmp(&self, other: &SpanContext) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for SpanContext

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for SpanContext

fn partial_cmp(&self, other: &SpanContext) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for SpanContext

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for SpanContext

impl Eq for SpanContext
