Struct Propagator

pub struct Propagator { /* private fields */ }

Propagator implements the Jaeger propagation format. See module level documentation for examples.

Implementations

impl Propagator

pub fn new() -> Self

Create a Jaeger propagator

pub fn with_custom_header(custom_header_name: &'static str) -> Self

Create a Jaeger propagator with custom header name

pub fn with_custom_header_and_baggage( custom_header_name: &'static str, custom_baggage_prefix: &'static str, ) -> Self

Create a Jaeger propagator with custom header name and baggage prefix

NOTE: it’ll implicitly fallback to the default header names when the name of provided custom_* is empty Default header-name is uber-trace-id and baggage-prefix is uberctx- The format of serialized contexts and baggages stays unchanged and does not depend on provided header name and prefix.

Trait Implementations

impl Clone for Propagator

fn clone(&self) -> Propagator

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Propagator

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

Formats the value using the given formatter.

impl Default for Propagator

fn default() -> Self

Returns the “default value” for a type.

impl TextMapPropagator for Propagator

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.
