25-25: Documentation needed for QBG integration

Since this is a draft PR introducing a new algorithm component, please provide:

1. Description of what QBG is and its purpose
2. Integration requirements and dependencies
3. Any performance implications or considerations

Consider adding these details to:

• PR description
• README in the QBG module
• Code documentation

rust/libs/algorithms/qbg/src/input.h (2)

32-39: Add parameter names to set_qbg_construction_parameters for clarity

Including parameter names in the function declaration enhances readability and helps developers understand the purpose of each parameter.

---

49-65: Include parameter names in set_qbg_build_parameters function

Providing parameter names in the function declaration improves code comprehension and maintainability.

rust/libs/algorithms/qbg/src/lib.rs (5)

59-62: Inconsistent Integer Types in set_hierarchical_clustering_init_mode

The function set_hierarchical_clustering_init_mode uses i16 for the parameter hierarchical_clustering_init_mode, whereas similar parameters in other functions use i32. Consider using consistent integer types to avoid potential issues.

---

63-65: Type Mismatch in set_number_of_second_objects

The parameter number_of_second_objects in set_number_of_second_objects is of type u32, while other similar parameters use usize. For consistency and to prevent potential bugs, consider using usize here as well.

---

109-130: Use Meaningful Values in Test Property Setters

In the test test_qbg, many property setters are assigned the value 1. Using more realistic and diverse values can improve the effectiveness of the test by covering a wider range of scenarios.

---

184-185: Simplify Return Statements in Test Functions

The lines return Ok(()); can be simplified to just Ok(()) for brevity and idiomatic Rust code.

Also applies to: 216-217

---

84-85: Clarify Parameter Naming and Types in new_index and new_prebuilt_index

The new_index function takes a Pin<&mut Property> as the second parameter named p, while new_prebuilt_index takes a bool named p. This overloading of p with different types may cause confusion. Consider renaming the boolean parameter to something more descriptive, like prebuilt, for clarity.

315-328: Missing Error Handling in Factory Functions

The factory functions new_index and new_prebuilt_index do not handle exceptions that may be thrown during object creation, potentially leading to unhandled exceptions.

Consider using exception handling to capture and report any errors during object creation:

std::unique_ptr<Index> new_index(const rust::String &path, Property &p)
{
    try
    {
        return std::make_unique<Index>(path, p);
    }
    catch (const std::exception &e)
    {
        // Handle exception, possibly log the error
        std::cerr << "Error creating Index: " << e.what() << std::endl;
        return nullptr;
    }
}

---

227-238: Use of const char* Instead of std::string in open_index

Passing cpath.c_str() may lead to issues if cpath goes out of scope before c_str() is used.

Since cpath is a local variable, it's safe here, but consider passing std::string directly if the underlying function accepts it, to reduce unnecessary conversions.

31-34: Add const correctness to getter methods.

The getter methods should be marked as const since they don't modify the object's state.

362-443: Add error case testing

The test only covers the happy path. Add tests for error cases:

• Invalid dimensions
• Empty vectors
• Out of bounds K values
• Invalid file paths

Add error case tests:

#[test]
fn test_ffi_qbg_errors() -> Result<()> {
    let path = "invalid/path".to_string();
    let mut p = Property::new();
    p.init_qbg_construction_parameters();
    
    // Test invalid path
    assert!(Index::new(&path, &mut p).is_err());
    
    // Test invalid dimensions
    p.set_dimension(0);
    assert!(Index::new(&"index".to_string(), &mut p).is_err());
    
    Ok(())
}
