pub unsafe extern "C" fn roaring_bitmap_portable_deserialize_size(
buf: *const c_char,
maxbytes: usize
) -> usize
Check how many bytes would be read (up to maxbytes) at this pointer if there is a bitmap, returns zero if there is no valid bitmap. This is meant to be compatible with the Java and Go versions. See format specification at https://github.com/RoaringBitmap/RoaringFormatSpec
