Crate saorsa_fec 

Saorsa FEC - High-Performance Erasure Coding

This crate provides exceptional performance systematic Reed-Solomon erasure coding with integrated encryption, storage, and content addressing.

Performance (v0.2.1)

• 1MB files: 1,193 MB/s (2.4x specification target)
• 10MB files: 7,545 MB/s (15x specification target)
• 50MB files: 5,366 MB/s (10.7x specification target)

Features

• High-Performance: reed-solomon-simd with SIMD acceleration (AVX2, AVX, SSE4.1, NEON)
• Systematic Encoding: Original data preserved in first k shares
• Authenticated Encryption: AES-256-GCM with deterministic nonces
• Content Addressing: Blake3-based deduplication
• Storage Pipeline: High-level API with pluggable backends
• Cross-Platform: Pure Rust with no C dependencies
