Struct HeaderMapExtractor

Source

pub struct HeaderMapExtractor<'a>(pub &'a HeaderMap);

Expand description

Adapter that lets the OpenTelemetry TextMapPropagator read from an axum/http HeaderMap.

The propagator API is generic over an opentelemetry::propagation::Extractor, which expects get(&str) -> Option<&str> and keys() -> Vec<&str> semantics. We provide the smallest possible bridge so we do not need the opentelemetry-http crate as an additional dependency.
