25-25: Documentation needed for QBG integrationSince this is a draft PR introducing a new algorithm component, please provide:
- Description of what QBG is and its purpose
- Integration requirements and dependencies
- Any performance implications or considerations
Consider adding these details to:
- PR description
- README in the QBG module
- Code documentation

32-39: Add parameter names toset_qbg_construction_parametersfor clarityIncluding parameter names in the function declaration enhances readability and helps developers understand the purpose of each parameter.
49-65: Include parameter names inset_qbg_build_parametersfunctionProviding parameter names in the function declaration improves code comprehension and maintainability.
rust/libs/algorithms/qbg/src/lib.rs (5)
59-62: Inconsistent Integer Types inset_hierarchical_clustering_init_modeThe function
set_hierarchical_clustering_init_modeusesi16for the parameterhierarchical_clustering_init_mode, whereas similar parameters in other functions usei32. Consider using consistent integer types to avoid potential issues.
63-65: Type Mismatch inset_number_of_second_objectsThe parameter
number_of_second_objectsinset_number_of_second_objectsis of typeu32, while other similar parameters useusize. For consistency and to prevent potential bugs, consider usingusizehere as well.
109-130: Use Meaningful Values in Test Property SettersIn the test
test_qbg, many property setters are assigned the value1. 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 FunctionsThe lines
return Ok(());can be simplified to justOk(())for brevity and idiomatic Rust code.Also applies to: 216-217
84-85: Clarify Parameter Naming and Types innew_indexandnew_prebuilt_indexThe
new_indexfunction takes aPin<&mut Property>as the second parameter namedp, whilenew_prebuilt_indextakes aboolnamedp. This overloading ofpwith different types may cause confusion. Consider renaming the boolean parameter to something more descriptive, likeprebuilt, for clarity.rust/libs/algorithms/qbg/src/input.cpp (2)
315-328: Missing Error Handling in Factory FunctionsThe factory functions
new_indexandnew_prebuilt_indexdo 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 ofconst char*Instead ofstd::stringinopen_indexPassing
cpath.c_str()may lead to issues ifcpathgoes out of scope beforec_str()is used.Since
cpathis a local variable, it's safe here, but consider passingstd::stringdirectly if the underlying function accepts it, to reduce unnecessary conversions.

rust/Cargo.toml (2)
24-24: LGTM! The workspace member addition follows project conventions.
The new qbg algorithm library is properly placed alongside other algorithm implementations (ngt, faiss).
24-24: Verify qbg library setup
Let's verify that the qbg library directory exists and has the required Cargo.toml configuration.
✅ Verification successful
QBG library setup is properly configured
The verification shows that the qbg library is correctly set up with:
- Directory structure present at
rust/libs/algorithms/qbg/ - Required files:
Cargo.toml,build.rs, andsrc/directory - Proper Cargo.toml configuration with:
- Package metadata
- Required dependencies (anyhow, cxx)
- Build dependencies (cxx-build, miette)
🏁 Scripts executed
The following scripts were executed for the analysis:

25-25: Verify QBG integration path and dependencies
The dependency path looks consistent with other algorithm dependencies, but let's verify the integration.
✅ Verification successful
QBG dependency path and integration verified
The QBG integration appears to be properly structured:
- QBG directory exists at the correct path (
rust/libs/algorithms/qbg) - The library implements a C++ bridge for QBG index construction and search
- Proper license headers and version metadata are present
- No direct usage in algorithm lib yet, which is expected for a draft PR

273-273: Incorrect Use of v.length() in append
The use of v.length() may be incorrect if v does not have a length() method or if it does not return the expected size.
Verify that v.length() correctly returns the number of elements in the slice. If not, use v.size() or adjust accordingly.
Run the following script to check for the correct method to retrieve the size of rust::Slice:
Ensure that the correct method is consistently used across the codebase.
✅ Verification successful
Let's search for actual usage patterns of rust::Slice in the codebase to understand how it's being used and what methods are available. I've also included a search for the specific vector construction pattern to see the surrounding context.
Use of v.length() is correct for rust::Slice
Looking at the codebase usage, v.length() is the correct method for rust::Slice. This is evidenced by its usage in qbg/src/input.cpp and supported by the fact that rust::Slice is a Rust-C++ bridge type where the Rust convention for getting collection size is length(). The code correctly constructs a vector from the slice's iterators and uses length() to get its size.

230-233: Uncomment and implement the destructor.
The destructor is currently commented out, which could lead to resource leaks. The index should be properly closed when the object is destroyed.
335-348: LGTM! Well-implemented factory functions.
The factory functions make good use of modern C++ practices with std::unique_ptr for automatic memory management.

🛠️ Refactor suggestion
Add parameter validation in setter methods.
The setter methods for construction parameters should validate their input values to ensure they are within acceptable ranges. For example, dimension and number_of_subvectors should be positive values.
Example implementation for one setter:
void Property::set_dimension(rust::usize dimension)
{
+ if (dimension == 0) {
+ throw std::invalid_argument("dimension must be positive");
+ }
qbg_construction_parameters->dimension = dimension;

Consider thread safety in search method.
The search method uses shared resources (index) without synchronization. If this method is called from multiple threads, it could lead to race conditions.
Consider adding mutex protection:
+#include <mutex>
+
class Index {
+private:
+ std::mutex search_mutex;
+
public:
void search(
rust::Slice<const rust::f32> v,
rust::usize k,

rust::f32 *distances)
{
+ std::lock_guard<std::mutex> lock(search_mutex);
// ... rest of the method
}

🛠️ Refactor suggestion
Add comprehensive parameter validation in bulk parameter setters.
The bulk parameter setters set_qbg_construction_parameters and set_qbg_build_parameters should validate their input parameters before setting them. This helps catch invalid configurations early.
Example implementation for set_qbg_construction_parameters:
void Property::set_qbg_construction_parameters(
rust::usize extended_dimension,
rust::usize dimension,
rust::usize number_of_subvectors,
rust::usize number_of_blobs,
rust::i32 internal_data_type,
rust::i32 data_type,
rust::i32 distance_type)
{
+ if (dimension == 0) {
+ throw std::invalid_argument("dimension must be positive");
+ }
+ if (number_of_subvectors == 0) {
+ throw std::invalid_argument("number_of_subvectors must be positive");
+ }
+ if (number_of_blobs == 0) {
+ throw std::invalid_argument("number_of_blobs must be positive");
+ }
+ if (extended_dimension < dimension) {
+ throw std::invalid_argument("extended_dimension must be >= dimension");
+ }
qbg_initialize_construction_parameters(qbg_construction_parameters);

Uncomment and implement the destructor.
The destructor is currently commented out, which will lead to resource leaks. The index needs to be properly closed when the object is destroyed.
Apply this fix:
Index::~Index()
{
- // close_index();
+ close_index();
}📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

23-30: Add const correctness to getter methods.The getter methods should be marked as const since they don't modify the object's state.
Apply this diff to improve const correctness:
- rust::u32 get_id() { return id; } - rust::f32 get_distance() { return distance; } + rust::u32 get_id() const { return id; } + rust::f32 get_distance() const { return distance; }
59-75: Improve parameter documentation for set_qbg_build_parameters.The method has many parameters with only partial documentation. Consider adding detailed parameter descriptions or using a parameter struct for better organization.
Example documentation format:
/** * Sets the QBG build parameters * @param init_mode Hierarchical clustering initialization mode * @param first_objects Number of objects for first level * ... */ void set_qbg_build_parameters(...);

🛠️ Refactor suggestion
Improve error handling in new method.
Using panic! for error handling is not idiomatic Rust. Consider propagating the error instead.
- let inner = match ffi::new_index(path, p.get_property()) {
- Ok(inner) => inner,
- Err(e) => panic!("{}", e),
- };
+ let inner = ffi::new_index(path, p.get_property())?;
Ok(Index { inner })📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

400-720: Enhance test coverage and assertionsThe test implementations primarily verify basic functionality but lack comprehensive assertions and error case testing.
Add the following improvements to tests:
- Verify search result ordering:
// In test_index() let search_results = index.search(vec.as_slice(), K, RADIUS, EPSILON)?; assert!( search_results.windows(2).all(|w| w[0].1 <= w[1].1), "Search results should be ordered by distance" );
- Add error case testing:
#[test] fn test_index_error_cases() -> Result<()> { let mut index = Index::new("nonexistent_path", &mut Property::new())?; assert!(index.get_object(999999).is_err(), "Should error on invalid ID"); Ok(()) }
- Test parameter validation:
#[test] #[should_panic(expected = "dimension must be positive")] fn test_invalid_dimension() { let mut p = Property::new(); p.set_qbg_construction_parameters(1, 0, 1, 1, 1, 1, 1); }

Add input validation for construction parameters
The set_qbg_construction_parameters method accepts parameters without validation, which could lead to undefined behavior in the C++ code.

number_of_subvectors: usize,
number_of_blobs: usize,

+ if dimension == 0 {
+ panic!("dimension must be positive");
+ }
+ if number_of_subvectors == 0 || number_of_subvectors > dimension {
+ panic!("invalid number_of_subvectors");
+ }
+ if extended_dimension < dimension {

Add safety documentation for FFI interface
The FFI interface uses unsafe code and raw pointers but lacks documentation about safety requirements. This is particularly important for functions like get_object that return raw pointers.
Add safety documentation for FFI functions, especially:
/// # Safety
///
/// Caller must ensure:
/// - The index is properly initialized
/// - The id is valid and within bounds
/// - The returned pointer must not outlive the Index instance
/// - The dimension returned by get_dimension() matches the actual object size
unsafe extern "C++" {
// ... existing declarations ...

| let dim = match self.inner.pin_mut().get_dimension() { | ||
| Ok(dim) => dim, | ||
| Err(e) => return Err(e), | ||

Document safety requirements for unsafe code
The get_object method uses unsafe code to create a slice from a raw pointer without clear documentation of safety requirements.
pub fn get_object(&mut self, id: usize) -> Result<&[f32], cxx::Exception> {
+ // SAFETY: We ensure safety by:
+ // 1. Getting the dimension first to ensure valid size
+ // 2. Checking that the pointer is non-null (done by Result)
+ // 3. The slice lifetime is tied to self, ensuring the underlying data remains valid
let dim = match self.inner.pin_mut().get_dimension() {
Ok(dim) => dim,
Err(e) => return Err(e),
};
match self.inner.pin_mut().get_object(id) {
Ok(v) => Ok(unsafe { slice::from_raw_parts(v, dim) }),
Err(e) => Err(e),
}
