Enum UnpackedSize

pub enum UnpackedSize {
    WriteToHeader(Option<u64>),
    SkipWritingToHeader,
}

Alternatives for handling unpacked size

Variants

WriteToHeader(Option<u64>)

If the value is Some(u64), write the provided u64 value to the header. There is currently no check in place that verifies that this is the actual number of bytes provided by the input stream. If the value is None, write the special 0xFFFF_FFFF_FFFF_FFFF code to the header, indicating that the unpacked size is unknown.

SkipWritingToHeader

Do not write anything to the header. The unpacked size needs to be stored elsewhere and provided when reading the file. Note that this is a non-standard way of writing LZMA data, but is used by certain libraries such as OpenCTM.
