Expand description

Methods to inject and extract a value as text into injectors and extractors that travel in-band across process boundaries.

Required Methods§

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

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

fn extract_with_context( &self, cx: &Context, 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 given Context is returned.

fn fields(&self) -> FieldIter<'_> ⓘ

Returns iter of fields used by TextMapPropagator

Provided Methods§

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

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

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.

Implementations on Foreign Types§

§

impl TextMapPropagator for BaggagePropagator

§

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

Encodes the values of the Context and injects them into the provided Injector.

§

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

Extracts a Context with baggage values from a Extractor.

§

fn fields(&self) -> FieldIter<'_> ⓘ

§

impl TextMapPropagator for TraceContextPropagator

§

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

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

§

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.

fn fields(&self) -> FieldIter<'_> ⓘ
