Struct opentelemetry_datadog::DatadogPropagator

pub struct DatadogPropagator { /* fields omitted */ }

Extracts and injects SpanContexts into Extractors or Injectors using Datadog’s header format.

The Datadog header format does not have an explicit spec, but can be divined from the client libraries, such as dd-trace-go

Example

use opentelemetry::global;
use opentelemetry_datadog::DatadogPropagator;

global::set_text_map_propagator(DatadogPropagator::default());

Implementations

impl DatadogPropagator

pub fn new() -> Self

Creates a new DatadogPropagator.

Trait Implementations

impl Clone for DatadogPropagator

fn clone(&self) -> DatadogPropagator

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DatadogPropagator

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

Formats the value using the given formatter.

impl Default for DatadogPropagator

fn default() -> DatadogPropagator

Returns the “default value” for a type.

impl TextMapPropagator for DatadogPropagator

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

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.
