Module storage 

Storage utilities for graph data.

This module provides compression and encoding utilities:

• dictionary - Dictionary encoding for strings with low cardinality
• delta - Delta encoding for sorted integer sequences
• bitpack - Bit-packing for small integers
• bitvec - Bit vector for boolean compression
• codec - Unified compression codec interface

Compression Strategies

Data Type	Recommended Codec	Compression Ratio
Sorted integers	DeltaBitPacked	5-20x
Small integers	BitPacked	2-16x
Strings (low cardinality)	Dictionary	2-50x
Booleans	BitVector	8x

Example

use graphos_core::storage::{TypeSpecificCompressor, CodecSelector};

// Compress sorted integers
let values: Vec<u64> = (100..200).collect();
let compressed = TypeSpecificCompressor::compress_integers(&values);
println!("Compression ratio: {:.1}x", compressed.compression_ratio());

// Compress booleans
let bools = vec![true, false, true, true, false];
let compressed = TypeSpecificCompressor::compress_booleans(&bools);
