# Algorithm.lzma

The LZMA compression algorithm, which is recommended for high-compression ratio.

## Declaration

```swift
case lzma
```

## Discussion

Discussion The Compression library implements the LZMA encoder at level 6 only.  This is the default compression level for open source LZMA, and provides excellent compression.  The LZMA decoder supports decoding data compressed with any compression level.
