包含有关在构建时和运行时压缩资产包时，资产包压缩支持的压缩方法、压缩级别和块大小的信息。
目前支持的格式通过静态属性公开。有三种支持的 BuildCompression 类型用于在构建期间压缩资产包（LZ4、LZMA 和未压缩），以及两种支持的运行时重新压缩方法（LZ4Runtime 和 UncompressedRuntime）。
其他资源：AssetBundle.RecompressAssetBundleAsync、资产包压缩、BuildAssetBundleOptions.ChunkBasedCompression、BuildAssetBundleOptions.UncompressedAssetBundle、BuildOptions.CompressWithLz4、CompressionType、缓存。
| LZ4 | LZ4HC “基于块” 压缩。 |
| LZ4Runtime | 用于运行时重新压缩的 LZ4 压缩。 |
| LZMA | LZMA 压缩。 |
| 未压缩 | 未压缩的资产包。 |
| UncompressedRuntime | 未压缩的资产包。 |
