RTSC - Real-time Synchronization Components crates.io page docs.rs page

Requirements for data synchronization in real-time applications differ from traditional high-load ones. The main difference is that real-time synchronization components must carefully respect and follow the traditional operating-system approach, avoid user-space spin-loops and other busy-waiting techniques (see Channels in Rust. Part 2 where such problems are clearly described).

§Components

This crate provides a pack of real-time-safe synchronization components for various typical and custom use-cases.

  • Data Buffer
  • Synchronization cells
  • Sync/async channels
  • Policy-based channels
  • Semaphore
  • Time tools

§Locking

On Linux the crate uses built-in priority-inheritance [pi::Mutex] implementation and re-exports this module as locking`.

On other platforms, all components use Mutex/Condvar synchronization primitives from parking_lot_rt - a real-time fork of the well-known parking_lot crate. This is a relatively safe Mutex/RwLock with minimal user-space spin-waiting. The module is re-exported as locking as well.

RTSC is a part of RoboPLC project.
