z.keyof()?

[ftzi]

I have an object. I want to validate that the given string is a keyof that object I have.

I tried the following:

z.enum(Object.keys(Items))
z.enum(Object.keys(Items) as (keyof typeof Items)[])

but they won't work. There is this answer elsewhere but it won't work: #839 (comment)

1. How can I achieve it in the best way?
2. There is the z.object({}).keyof(). Should Zod have the z.keyof() to achieve what I am trying to do? Seems a good thing to have in the library.

Edit: I managed to get this working z.custom<keyof typeof Items>((v) => Object.keys(Items).includes(v as string)), but I still think we should have z.keyof!
