Module index 

Main DiskANN index

Provides the primary user-facing API for DiskANN, orchestrating all components:

• Graph structure (Vamana graph)
• Storage backend (disk I/O)
• Search algorithm (beam search)
• Index building (incremental construction)

Example

use oxirs_vec::diskann::{DiskAnnIndex, DiskAnnConfig};

// Create index
let config = DiskAnnConfig::default_config(128);
let mut index = DiskAnnIndex::new(config, "/path/to/index")?;

// Add vectors
index.add("vec1", vec![...])?;
index.add("vec2", vec![...])?;

// Build and save
index.build()?;

// Search
let results = index.search(&query, 10)?;
