Function lzzzz::lz4f::max_compressed_size

#[must_use]pub fn max_compressed_size(original_size: usize, prefs: &Preferences) -> usize

Calculates the maximum size of the compressed output.

If original_size is too large to compress, this returns 0.

Returned values are reliable only for compress or compress_to_vec. Streaming compressors may produce larger compressed frames.
