68-72: LGTM! Consider adding documentation.The refactored type name determination logic is well-structured and correctly handles both Option and direct types. This change improves code organization by consolidating the type handling logic.
Consider adding a doc comment explaining the type name determination logic:
+ // Determine the underlying type name, handling both Option<T> and direct T types + // For Option<T>, extracts and returns the name of T + // For direct types, returns the type name as is let type_name = if let Some(value) = &has_option { get_type_name(*value) } else { get_type_name(&field.ty) };

78-107: Consider reducing code duplication in map insertion logic.While the map insertion logic is functionally correct, there's noticeable duplication in the handling of different types. Consider extracting the common map insertion pattern into a helper function.
Here's a suggested refactor:
impl #struct_name { // Helper function to handle map insertion with proper type conversion fn insert_value<T: ToString>( map: &mut HashMap<CheetahString, CheetahString>, key: &'static str, value: &T, is_string_type: bool, ) { let value_str = if is_string_type { value.to_string() } else { value.to_string() }; map.insert( CheetahString::from_static_str(key), CheetahString::from_string(value_str), ); } }This would simplify the map insertion code to:
if let Some(ref value) = self.#field_name { Self::insert_value(&mut map, Self::#static_name, value, type_name == "String"); }

Line range hint 1-236: Verify handling of all request header types.
Let's ensure that all request header types in the codebase are properly handled by this refactored codec implementation.
✅ Verification successful
Let me gather more specific information about the field types used in these request headers.
Based on the analysis of the request headers, I can now provide a final response:
The request header codec implementation properly handles all used types
The implementation correctly handles all field types found in the request headers:
- Basic types:
i32,i64are handled via theparseandto_stringmethods CheetahStringhas dedicated handling in bothto_mapandfrom_mapOption<T>wrapping of these types is properly managed- All fields are correctly converted to camelCase for Java compatibility
The macro implementation in request_header_custom.rs covers all cases found in the actual usage across the codebase, including:
- Required and optional fields
- String types (both native and CheetahString)
- Numeric types with proper parsing
- Proper error handling for missing required fields

# Search for potential custom type fields that might need special handling
