Module prefetch 

Chunk prefetching for improved performance.

This module provides intelligent chunk prefetching that predicts which chunks will be needed next and pre-loads them into memory.

Examples

use chie_core::prefetch::{ChunkPrefetcher, PrefetchConfig};

let config = PrefetchConfig::default();
let prefetcher = ChunkPrefetcher::new(config);

// Record access pattern (automatically predicts next chunks)
let predicted = prefetcher.record_access("QmContent123", 0).await;
println!("Predicted chunks after access 0: {:?}", predicted);

let predicted = prefetcher.record_access("QmContent123", 1).await;
println!("Predicted chunks after access 1: {:?}", predicted);

// Cache a chunk for faster retrieval
prefetcher.put_cached("QmContent123", 2, vec![1, 2, 3, 4]).await;

// Retrieve from cache
if let Some(data) = prefetcher.get_cached("QmContent123", 2).await {
    println!("Retrieved {} bytes from cache", data.len());
}
