Module cache 

Query caching and prepared statement management.

This module provides utilities for caching SQL queries and managing prepared statements to improve performance.

Query Cache

The QueryCache stores recently executed queries by their hash, allowing fast lookup of previously built SQL strings.

use prax_query::cache::QueryCache;

let cache = QueryCache::new(1000);

// Cache a query
cache.insert("users_by_id", "SELECT * FROM users WHERE id = $1");

// Retrieve later
if let Some(sql) = cache.get("users_by_id") {
    println!("Cached SQL: {}", sql);
}
