Expand description
An iterator that generates control words from repetition and definition levels
“Control word” is just a fancy term for a single u8/u16/u32 that contains both the repetition and definition in it.
In the large majority of case we only need a single byte to represent both the repetition and definition levels. However, if there is deep nesting then we may need two bytes. In the worst case we need 4 bytes though this suggests hundreds of levels of nesting which seems unlikely to encounter in practice.
