Struct OtlpHttpExporter 

pub struct OtlpHttpExporter { /* private fields */ }

Send spans to an OTLP-compatible collector over HTTP (JSON encoding).

Compatible with Jaeger ≥ 1.35, Grafana Tempo, and OpenTelemetry Collector. Point at http://localhost:4318 (the default OTLP HTTP port).

Implementations

impl OtlpHttpExporter

pub fn new(endpoint: &str, service_name: &str, service_version: &str) -> Self

endpoint is the collector’s base URL (http://localhost:4318, spans go to /v1/traces under it) or the full traces URL ending in /v1/traces. https:// works too.

pub fn with_headers(self, headers: Vec<(String, String)>) -> Self

Send these headers with every export (an API key, for instance).

pub fn url(&self) -> &str

The URL spans are POSTed to.

pub fn build_body(&self, spans: &[SpanData]) -> String
