velesdb-core 1.9.2

//! Synchronization primitives with loom support for concurrency testing.
//!
//! This module provides type aliases that switch between standard library
//! sync primitives and loom's mocked versions based on the `loom` feature flag.
//!
//! # Usage
//!
//! ```rust,no_run
//! use velesdb_core::sync::{Arc, RwLock, Mutex};
//!
//! // Works with both std and loom
//! let data = Arc::new(RwLock::new(42));
//! ```
//!
//! # Testing with Loom
//!
//! ```bash
//! cargo +nightly test --features loom --test loom_tests
//! ```
