Function hpk::compress

pub fn compress(
    options: &CompressOptions, 
    r: &mut dyn Read, 
    w: &mut dyn Write
) -> Result<u64, HpkError>

Compresses the data with the encoder used

if no data is written at all the hpk compression header is written without any chunks it's the same behaviour as in a DLC file for Tropico 4
