SnappyLib 1.1.7

Snappy, a fast compressor/decompressor.

This is the PInvoke wrapper over the implementation of the compression / decompression algorithm in the c ++ library from Google (https://github.com/google/snappy version 1.1.7).

Basic usage

var source = "У попа была собака он её любил, она съела кусок мяса он её убил.";
var sourceData = System.Text.Encoding.UTF8.GetBytes(source);
var compressData = new byte[1024];
var uncompressData = new byte[1024];

var compressedSize = SnappyLib.Snappy.Compress(sourceData, 0, sourceData.Length, compressData, 0, compressData.Length);
Assert.AreEqual(100, compressedSize);

var uncompressedSize = SnappyLib.Snappy.Uncompress(compressData, 0, compressedSize, uncompressData, 0, uncompressData.Length);
Assert.AreEqual(sourceData.Length, uncompressedSize);
Assert.IsTrue(new Span<byte>(sourceData).SequenceEqual(new Span<byte>(uncompressData, 0, uncompressedSize)));

var maxCompressedSize = SnappyLib.Snappy.MaxCompressedLength(sourceData.Length);
Assert.IsTrue(maxCompressedSize >= compressedSize);

var calculatedUncompressedSize = SnappyLib.Snappy.UncompressedLength(compressData, 0, compressedSize);
Assert.AreEqual(sourceData.Length, calculatedUncompressedSize);

var dcompressedDataValidationStatus = SnappyLib.Snappy.ValidateCompressedBuffer(compressData, 0, compressedSize);
Assert.AreEqual(dcompressedDataValidationStatus, SnappyLib.SnappyStatusEnum.SNAPPY_OK);
