Are the examples up-to-date? basic-otlp-http example not working

[ghost]

I was following the example here https://github.com/open-telemetry/opentelemetry-rust/blob/main/examples/basic-otlp-http/src/main.rs, but my program doesn't compile.

tracing here https://github.com/open-telemetry/opentelemetry-rust/blob/main/examples/basic-otlp-http/src/main.rs#L13 appears nowhere to be found in the docs https://docs.rs/opentelemetry-otlp/0.8.0/src/opentelemetry_otlp/lib.rs.html#251.

I know the config.toml https://github.com/open-telemetry/opentelemetry-rust/blob/main/examples/basic-otlp-http/Cargo.toml is using the local package while I am using the package hosted at crates.io. Could it be mismatched versions?

No, it hasn't been updated as shown https://docs.rs/opentelemetry-otlp/0.8.0/src/opentelemetry_otlp/lib.rs.html#175

but in GitHub https://github.com/open-telemetry/opentelemetry-rust/blob/main/opentelemetry-otlp/src/lib.rs#L175

I was exploring opentelemtry-rust as a tracing solution for my Rust software but I don't think it's production-ready, not like Vector.

Now I'm exploring just tracing, exporting to file and ingest through Vector or directly to Jaeger in case anybody is doing something similar.

Yes, we are still working towards GA on the tracing part now, the opentelemetry-collector is also in pre 1.0 status. The examples in the main branch use the main branch's code rather than the latest released code. There was a change introduced to allow the OTLP pipeline to send metrics and tracing info to the collector. #585.

Examples that use the latest released version can be found here.

Looks like you already took another route. But if you still want to explore opentelemetry and need some help. Feel free to reopen the issue and I can help with that.
