Type Alias BlockStateIntegerRepr 

pub type BlockStateIntegerRepr = u16;

The type that’s used internally to represent a block state ID.

This should be either u16 or u32. If you choose to modify it, you must also change it in azalea-block-macros/src/lib.rs.

This does not affect protocol serialization, it just allows you to make the internal type smaller if you want.
