## 📖 Overview
**RustFS Rio** provides high-performance asynchronous I/O operations for the [RustFS](https://rustfs.com) distributed
object storage system. It implements efficient data streaming, encryption, compression, and integrity checking with
zero-copy operations and optimized buffering strategies.
> **Note:** This is a performance-critical submodule of RustFS that provides essential I/O capabilities for the
> distributed object storage system. For the complete RustFS experience, please visit
> the [main RustFS repository](https://github.com/rustfs/rustfs).
## ✨ Features
### 🚀 High-Performance I/O
- **Zero-Copy Operations**: Efficient data movement without unnecessary copying
- **Async Streaming**: Non-blocking streaming I/O with backpressure handling
- **Vectored I/O**: Scatter-gather operations for improved throughput
- **Buffer Management**: Intelligent buffer pooling and reuse
### 🔐 Cryptographic Operations
- **AES-GCM Encryption**: Hardware-accelerated encryption/decryption
- **Streaming Encryption**: Encrypt data on-the-fly without buffering
- **Key Management**: Secure key derivation and rotation
- **Digital Signatures**: Data integrity verification
### 📦 Compression Support
- **Multi-Algorithm**: Support for various compression algorithms
- **Streaming Compression**: Real-time compression during transfer
- **Adaptive Compression**: Dynamic algorithm selection based on data
- **Compression Levels**: Configurable compression vs. speed tradeoffs
### 🔧 Data Integrity
- **CRC32 Checksums**: Fast integrity checking
- **MD5 Hashing**: Legacy compatibility and verification
- **Merkle Trees**: Hierarchical integrity verification
- **Error Correction**: Automatic error detection and correction
