for this specific use case, you may use:

---@class A<B>: { b: B }

---@type A<string>
local a = {}

print(a.b) --> (field) a.b: string

• this roughly means that A<B> is a table like { b: B }
• AFAIK luals's generic class support is quite limited currently
  and seems you can't directly use that generic variable inside @field

ps:
for questions / q&a, please consider using the discussion: https://github.com/LuaLS/lua-language-server/discussions
issue page is for tracking bugs / incorrect behavior / etc. 😅

edit:
I assume this is a feature request, so you may keep it open. 😂
Though I don't think maintainers will have time to finish it, given that it has workarounds/alternatives, and not a serious bug.
