Depth validation on input fields

[P4sca1]

Is there any way to validate the depth of input object types?

E.g. having a recursive input type like this (used for Prisma filtering):

interface MyRecursiveFilter {
  id?: string
  name?: string
  // ...
  AND?: MyRecursiveFilter[]
  OR?: MyRecursiveFilter[]
}

I want to make sure that when a client uses this input type, the AND and OR is not nested more than x times.
Writing the validation itself should be no problem, but where do I write the validation logic?

I solved this using an extra input type.

function createGameFilter(
	t: InputFieldBuilder<TypesWithDefaults, 'InputObject'>
) {
	return {
		short: t.field({ type: StringFilter }),
		name: t.field({ type: StringFilter }),
		description: t.field({ type: StringFilter }),
		updatedAt: t.field({ type: DateTimeFilter }),
		createdAt: t.field({ type: DateTimeFilter }),
	}
}

export const GameFilter = builder.inputType('GameFilter', {
	fields: (t) => ({
		...createGameFilter(t),
		AND: t.field({
			type: [NestedGameFilter],
			required: { list: false, items: true },
		}),
		OR: t.field({
			type: [NestedGameFilter],
			required: { list: false, items: true },
		}),
	}),
})

export const NestedGameFilter = builder.inputType('NestedGameFilter', {
	fields: (t) => createGameFilter(t),
})
