Infer type from other property

[nehalist]

Hey,

quick question: how can I achieve this:

interface Obj {
  schema: z.ZodSchema;
  defaultValue: any /** should be the inferred type of `schema` */;
}

const a: Obj = {
  schema: z.string(),
  defaultValue: 123, // should cause an error since it's no string
}

Using z.infer<Obj["schema"]> unfortunately doesn't work (defaultValue becomes any) and I'm running out of ideas how to achieve this.

Thanks!
