Related Problems?

Hi,

We just migrated Stalwart from opentelemetry 0.25 to 0.29 and noticed two issues that I briefly explained in #2260:

• We use our custom logging backend rather than tracing and global::set_error_handler has been removed.
• We also use run own own span, log and metrics export task and the Default trait has been removed from SdkLogRecord. In order to be able to generate a SdkLogRecord we now need to do SdkLoggerProvider::builder().build().logger("stalwart").create_log_record() which is not awful but it would be much nicer if SdkLogRecord::new was made public or the Default trait was added.

Describe the solution you'd like:

I propose to:

• Re-implement global::set_error_handler (or similar) and place it behind a Cargo feature, which will be disabled by default. I agree that most users will use tracing.
• Make SdkLogRecord::new public or add the Default trait to SdkLogRecord.

I'm not familiar with the internals of this crate but if you prefer I can submit a PR for these.
