[Feature]: OTLP File Exporter #2602
Description
Related Problems?
Prior to #2040, the opentelemetry-stdout crate was able to export in a format compatible with the OTLP File Exporter specification here. Passing in a file as the writer allowed the exporter to export to a file, and the default JSON serializer was compatible with the spec (example setup here). Since #2040, a writer can no longer be passed in, and the format is not JSON.
Describe the solution you'd like:
I'd love to see a FileExporter that complies with https://opentelemetry.io/docs/specs/otel/protocol/file-exporter.
Considered Alternatives
No response
Additional Context
There is some discussion here about whether this functionality is strictly required for SDKs.
I may have to roll my own OTLP File Exporter soon. I could potentially contribute it back to this library if desired.

Happy to host it in the contrib repo. (Or even this repo.)
Feel free to send a PR.

@joshwlewis hi, are you actively working on this?

@berkus, no I'm not working on it at the moment. I have aspirations to do it, but haven't found the bandwidth just yet. Feel free to tackle it if you want. If it's of interest or help, I did roll my own (for traces only): https://github.com/heroku/libcnb.rs/blob/108faf180d8368011eae62c0fc5acc28b8d8119a/libcnb/src/tracing.rs#L126-L176
