Expand description

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

Required Methods§

source

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

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

source

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.

source

fn fields(&self) -> FieldIter<'_> ⓘ

Returns iter of fields used by TextMapPropagator

Provided Methods§

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.
