Module locks 

Lock-aware querying for thread-safe data structures.

This module provides support for querying data behind locks (RwLock, Mutex) without copying. It works with both std and tokio locks (when enabled).

Features

• Query Arc<RwLock<T>> and Arc<Mutex<T>> directly
• No data copying - works with lock guards
• Extensible for tokio::sync locks
• Works with HashMap, Vec, and other collections of locks

Example

use std::sync::{Arc, RwLock};
use std::collections::HashMap;
use rust_queries_core::{locks::LockQueryExt, LazyQuery};

type ProductMap = HashMap<String, Arc<RwLock<Product>>>;

let products: ProductMap = /* ... */;

// Query without copying!
let electronics: Vec<_> = products
    .query_locks()
    .where_(Product::category_r(), |cat| cat == "Electronics")
    .collect();
