143-143: Excellent condition optimization!

The simplified condition !request_header.batch.unwrap_or(false) is a more elegant way to handle both None and Some cases, replacing the verbose request_header.batch.is_none() || !request_header.batch.unwrap(). This change:

• Reduces cognitive complexity
• Maintains the same logical behavior
• Improves code readability

Consider adding a comment explaining the condition's purpose for better maintainability:

+    // Process as single message if batch flag is not set or false
     if !request_header.batch.unwrap_or(false) {
