pub struct CompactCountULE(/* private fields */);
Expand description

CompactCountULE is a type optimized for efficient storing and deserialization of CompactCount using the ZeroVec model.

The serialization model packages the pattern item in one byte.

The first bit (b7) is used to determine count_type. If the bit is 0, then, then the type is Standard. If the bit is 1, then, then the type is AlphaNextToNumber.

The last three bits (b2, b1 & b0), are used to determine the count: 000 -> Count::Zero 001 -> Count::One 010 -> Count::Two 011 -> Count::Few 100 -> Count::Many 101 -> Count::Other

The other bits (b6,b5,b4,b3) must always be zeros.
