A high-speed, high-performance, high-concurrency data structures library for Rust.

Supersonic provides blazingly fast, thread-safe data structures optimized for demanding multi-threaded environments. Built with fine-tuned memory ordering, lock-free reads, and reactive capabilities, Supersonic is designed for scenarios where microsecond latency and maximum throughput are critical.

📋 Table of Contents

✨ Features

  • 🔥 High-Speed Operations: Lock-free reads and optimized memory ordering for minimal latency
  • ⚡ High Performance: Fine-tuned atomic operations with Relaxed + Release patterns (5-20% faster than naive implementations)
  • 🔀 High Concurrency: Designed for heavy multi-threaded workloads with minimal contention
  • 🔄 Reactive Capabilities: Share data modifications across references or create isolated copies
  • 📦 Zero-Copy Cloning: Arc-based sharing makes cloning extremely cheap
  • 🎯 Rich API: Stack, queue, list operations plus advanced features like slicing, splitting, and draining
  • 🔒 Thread-Safe: All operations are safe to call from multiple threads concurrently
  • 📊 Serialization: Built-in bincode support for efficient binary serialization

📦 Installation

Add supersonic to your Cargo.toml:

[dependencies]
supersonic = "0.1.0"

Or use cargo add:

cargo add supersonic

🚀 Quick Start

use supersonic::sequence::prelude::*;
use anyhow::Result;

#[tokio::main]
async fn main() -> Result<()> {
    // Create a new sequence with capacity 10
    let seq = Sequence::<i32>::allocate(10).await;

    // Push elements (stack-like)
    seq.push(Candidate::Value(1)).await;
    seq.push(Candidate::Value(2)).await;
    seq.push(Candidate::Value(3)).await;

    // Get element at index
    let value = seq.get(1, true).await?;
    println!("Element at index 1: {:?}", value);

    // Pop from end
    let popped = seq.pop().await;
    println!("Popped: {:?}", popped);

    // Queue operations
    seq.enqueue(Candidate::Value(4)).await;
    let dequeued = seq.dequeue().await?;
    println!("Dequeued: {:?}", dequeued);

    // Slice and split
    let slice = seq.slice(Some(0), Some(2), None).await;
    let (first, second) = seq.split(1).await;

    // Create snapshot
    let snapshot = seq.snapshot().await;
    println!("Snapshot: {:?}", snapshot);

    Ok(())
}

🗂️ Data Structures

Sequence<T>

A high-speed, high-performance, high-concurrency, lock-free, thread-safe, reactive sequence data structure.

Key Features

  • Lock-Free Reads: Most read operations use atomic loads without acquiring locks
  • Memory Ordering Optimization: Uses Relaxed ordering under locks with Release fences for 5-20% performance improvement
  • Dynamic Growth: Automatically resizes when capacity is exceeded
  • Dual Nature: Supports both reactive (shared) and non-reactive (isolated) operations

Reactivity

Reactive operations (extract, slice, split, reverse, modify) create sequences that share underlying Arc<RwLock<T>> references. Modifications through one sequence are visible through all others.

Non-reactive operations (set, non-reactive versions of extract/slice/split/reverse) create independent copies with isolated state.

Traits Implemented

  • Allocation<T> - Allocate new sequences
  • Operation<T> - Core operations (get, set, insert, remove, append)
  • Reactive<T> - Reactive operations with shared state
  • NonReactive<T> - Non-reactive operations with isolated state
  • Stack<T> - LIFO operations (push, pop, peek)
  • Queue<T> - FIFO operations (enqueue, dequeue)
  • Drain<T> - Drain ranges of elements
  • SnapShot<T> - Create Vec snapshots
  • Bincode<T> - Binary serialization
  • Equality<T> - Equality comparison strategies
  • Length - Length operations

Performance Characteristics

Operation Complexity Notes
Clone O(1) Only clones Arc pointers
Length/Capacity O(1) Simple atomic loads
Get O(1) Direct array access
Set O(1) Direct array access with atomic swap
Append Amortized O(1) May trigger resize
Insert O(n) Requires shifting right
Remove O(n) Requires shifting left
Push/Pop Amortized O(1) Stack operations
Enqueue Amortized O(1) Queue insert
Dequeue O(n) Queue remove with shift

⚡ Performance

Supersonic achieves high performance through several optimizations:

Memory Ordering Optimization

All atomic operations under locks use Relaxed ordering with a final Release operation to publish changes. This eliminates unnecessary memory fences while maintaining correctness:

// Traditional approach
container.slots[i].store(ptr, Acquire);  // Extra fence!

// Optimized approach
container.slots[i].store(ptr, Relaxed);  // Under lock
container.length.store(len, Release);    // Publishes all changes

Performance gains:

  • High contention scenarios: 15-20% improvement
  • Moderate use: 5-10% improvement
  • Bulk operations (slice, split, drain): 10-20% improvement

Lock-Free Reads

Read operations use atomic loads without acquiring locks when synchronization is optional, enabling true concurrent reads with zero contention.

🎯 Use Cases

Supersonic is ideal for demanding, high-throughput, low-latency scenarios:

High-Frequency Trading (HFT)

Order books, tick data streams, and trade execution queues where microsecond latency matters.

Real-Time Analytics

Processing streaming data from sensors, logs, or metrics with multiple concurrent readers/writers.

Game Engines

Entity component systems, event queues, and shared game state across game loop threads.

Network Servers

Connection pools, request queues, and message buffers in high-concurrency web servers and proxies.

Scientific Computing

Shared work queues in parallel algorithms, particle simulations, and distributed computation.

Audio/Video Processing

Real-time sample buffers, frame queues, and DSP pipelines where bounded latency prevents glitches.

Blockchain/Distributed Systems

Transaction pools, mempool management, and consensus message queues.
