Struct SpanContext 

pub struct SpanContext {
    pub process_id: ProcessId,
    pub span_id: SpanId,
}

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

Fields

process_id: ProcessId

The id of the process this span belongs to.

span_id: SpanId

The unique id of this span.

Implementations

impl SpanContext

pub fn new(process_id: ProcessId, span_id: SpanId) -> SpanContext

Creates a new SpanContext with the given ProcessId and SpanId.

Examples

use veecle_telemetry::{ProcessId, SpanId, SpanContext};

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

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

let span_context = SpanContext::current();
assert!(span_context.is_some());

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 Display for SpanContext

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

Formats the value using the given formatter.

impl FromStr for SpanContext

type Err = ParseSpanContextError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<SpanContext, <SpanContext as FromStr>::Err>

Parses a string s to return a value of this type.

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
