How to add new data type?

[NagelRing]

I use the Tarantool database. They expand the types of LUA data and add the type "cdata". How to embed a new data type in that plugin?

For example, I make a description of the functions of the "clock" module from Tarantool.

The plugin highlights the word "cdata", but correctly uses it in the hints.

I can simply disable the syntax check of this string, but I would like to add a new type.

In particular, for the autocomplete it when comparing type(v) == 'cdata'

---@alias type type | "cdata"
