Auto Allocator - Zero-Configuration Memory Optimization

Just add one line and get optimal memory performance automatically!

Auto-allocator automatically selects the best memory allocator for your platform and hardware, giving you significant performance improvements without any configuration or code changes.

Why Auto Allocator?

• 🚀 Instant Performance: Up to 1.6x faster allocation in multi-threaded applications
• 🔧 Zero Configuration: Works perfectly out-of-the-box, no setup required
• 🌍 Universal Compatibility: Optimizes across all platforms - servers, desktop, mobile, embedded, WASM
• 🧠 Platform Intelligence: Automatically chooses the best allocator for each platform
• ⚡ Production Ready: Used safely in high-performance production environments

Quick Start

Step 1: Add to your Cargo.toml:

[dependencies]
auto-allocator = "*"

Step 2: Add one line to your main.rs:

use auto_allocator; // That's it! 🎉

fn main() {
    // Your code automatically runs with optimal memory performance
    let data = vec![1, 2, 3, 4, 5];
    println!("Memory allocations are now optimized!");
}

That’s literally all you need! Auto-allocator handles everything else automatically.

What You Get
