index_name

std::string index_name() const;
Returns the name of the index.

​

IndexType index_type() const;
Returns the type of the index (for example, ivf, ivfpq, or ivfflat).

​
index_config

IndexConfig* index_config() const;
Returns a pointer to the index configuration.

​
ListIDs

std::vector<std::string> ListIDs();
Returns a vector containing all item IDs currently stored in the index.

Exceptions

  • std::runtime_error: Thrown if an error occurs during retrieval.

​
NumVectors

size_t NumVectors();
Returns the total number of vectors currently stored in the encrypted index.

​
Returns

size_t: The number of vectors in the index.

​
Exceptions

  • Throws if the index was not created or loaded yet.

Example Usage

// Get the number of vectors in the index
size_t vector_count = index->NumVectors();
std::cout << "Index contains " << vector_count << " vectors" << std::endl;

// Use count for validation or progress reporting
if (vector_count == 0) {
    std::cout << "Index is empty, consider adding vectors" << std::endl;
}
