This directory holds files for testing zstd.NewReader. Each one is a Zstandard compressed file named as hash.arbitrary-name.zst, where hash is the first eight hexadecimal digits of the SHA256 hash of the expected uncompressed content: zstd -d < 1890a371.gettysburg.txt-100x.zst | sha256sum | head -c 8 1890a371 The test uses hash value to verify decompression result.
