Implementations

impl W3CTraceContext

pub fn new_root() -> Self

Create a new root trace context

pub fn new_child(&self) -> Self

Create a child span context

pub fn from_traceparent(header: &str) -> ObservabilityResult<Self>

Create from W3C traceparent header

pub fn from_headers( headers: &HashMap<String, String>, ) -> ObservabilityResult<Option<Self>>

Create from W3C headers

pub fn to_traceparent(&self) -> String

Generate W3C traceparent header value

pub fn to_headers(&self) -> HashMap<String, String>

Generate W3C headers for propagation

pub fn is_sampled(&self) -> bool

Check if the trace is sampled

pub fn set_sampled(&mut self, sampled: bool)

Set sampling flag

pub fn add_trace_state(&mut self, key: &str, value: &str)

Trait Implementations

impl Clone for W3CTraceContext

fn clone(&self) -> W3CTraceContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for W3CTraceContext

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

Formats the value using the given formatter.

impl Display for W3CTraceContext

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

Formats the value using the given formatter.

impl PartialEq for W3CTraceContext

fn eq(&self, other: &W3CTraceContext) -> 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.
