Propagates SpanContexts in W3C TraceContext format.

Implementations§

source§

impl TraceContextPropagator

source

pub fn new() -> TraceContextPropagator

Create a new TraceContextPropagator.

Trait Implementations§

impl Debug for TraceContextPropagator

source§

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

Formats the value using the given formatter. Read more
source§

impl Default for TraceContextPropagator

source§

fn default() -> TraceContextPropagator

Returns the “default value” for a type. Read more
source§

impl TextMapPropagator for TraceContextPropagator

source§

fn inject_context(&self, cx: &Context, injector: &mut dyn Injector)

Properly encodes the values of the SpanContext and injects them into the Injector.

source§

fn extract_with_context( &self, cx: &Context, extractor: &dyn Extractor ) -> Context

Retrieves encoded SpanContexts using the Extractor. It decodes the SpanContext and returns it. If no SpanContext was retrieved OR if the retrieved SpanContext is invalid then an empty SpanContext is returned.

source§

fn fields(&self) -> FieldIter<'_>

Returns iter of fields used by TextMapPropagator
source§

fn inject(&self, injector: &mut dyn Injector)

Properly encodes the values of the current Context and injects them into the Injector.
source§

fn extract(&self, extractor: &dyn Extractor) -> Context

Retrieves encoded data using the provided Extractor. If no data for this format was retrieved OR if the retrieved data is invalid, then the current Context is returned.
