A helpful technique when dealing with verbose logging scenarios is to define a purpose-built struct.

For example, I found this especially useful when I needed to log both a JSON payload and an associated error. Instead of spreading the information across multiple log statements, I encapsulated it in a single struct, making the logs more concise and easier to read through the inspector.
