Zstandard.Native

Ultra-fast Native AOT-safe Zstandard wrapper for .NET 8, .NET 9, and .NET 10 — zero-allocation Span<byte> APIs, source-generated [LibraryImport] P/Invoke, and hardware-accelerated buffer paths via AVX-512 / AVX10.2 and ARM64 SVE.

Install

dotnet add package Zstandard.Native

You also need a libzstd binary on the loader path. See Native runtime binaries for options (companion runtime package, bring-your-own, or system package manager).

Quick start

One-shot compress / decompress

using Zstandard.Native;

ReadOnlySpan<byte> src = File.ReadAllBytes("data.bin");

byte[] compressed = new byte[ZstdCompressor.GetCompressBound(src.Length)];
int n = ZstdCompressor.Compress(src, compressed, compressionLevel: 3);

byte[] back = new byte[src.Length];
ZstdCompressor.Decompress(compressed.AsSpan(0, n), back);

Streaming with context reuse

using var compressor = new ZstdStreamCompressor(compressionLevel: 3);
Span<byte> outBuf = stackalloc byte[ZstdStreamCompressor.RecommendedOutputSize];

foreach (var frame in frames)
{
    compressor.Reset(); // reuses ZSTD_CCtx — no allocation
    var r = compressor.Compress(frame.Span, outBuf, ZstdEndDirective.End);
    sink.Write(outBuf[..r.BytesWritten]);
}

Features

  • Zero allocations on the hot path — Span<byte>-only public API
  • Native AOT compatible — every IL2xxx/IL3xxx warning is an error in CI; no reflection, no marshalling shims
  • SafeHandle lifetime management for ZSTD_CCtx / ZSTD_DCtx — finalizer-safe even on process abort
  • Streaming with Reset() context reuse — skips ZSTD_createCCtx per frame
  • Hardware acceleration via Vector512 (AVX-512 / AVX10.2) and SVE (ARM64 variable-width) for buffer scrub operations
  • Targets libzstd ≥ 1.5.0 on win-x64, win-arm64, linux-x64, linux-arm64, osx-x64, osx-arm64
