refactor trace exporter errors to use template pattern

Open ekump opened this issue 3 months ago • 2 comments

What does this PR do?

TraceExporterError is now template based. The error message is static and dynamic context is included separately as key value pairs. In Rust, the Display trait can be used to get a string that combines the template and context for standard error logging scenarios. For cases where we want to ensure we don't include any dynamic content the template field can be used. The FFI layer has also been updated to separate template and context.

Motivation

Sometimes we don't want to log strings with dynamic content in them.

Additional Notes

Breaking change for FFI API users For ExporterError msg: *mut c_char* has been replaced with msg_template: *const c_char. New fields have also been added.

Possible Breaking change for Rust API users The public API changes to TraceExporterError are additive, but the format of the string returned by the Display trait has changed.

How to test the change?

Describe here in detail how the change can be validated.
