Module lzzzz::lz4

Extremely fast compression algorithm.

Acceleration factor

Some functions take the 'acceleration factor' as i32.

Larger value increases the processing speed in exchange for the loss of compression ratio.

// The default factor is 1 so both have a same meaning.
lz4::compress_to_vec(data, &mut buf, lz4::ACC_LEVEL_DEFAULT)?;
lz4::compress_to_vec(data, &mut buf, 1)?;

// Factors lower than 1 are interpreted as 1 so these are also same as above.
lz4::compress_to_vec(data, &mut buf, 0)?;
lz4::compress_to_vec(data, &mut buf, -100)?;

// Faster but less effective compression.
lz4::compress_to_vec(data, &mut buf, 1000)?;
