How to check if a value is duplicated in validator?

[AleDiBernardo]

I have this validator for contract_status table, how can i add unique() validation to 'code' column?

import vine from '@vinejs/vine'


export const createContractStatusValidator = vine.compile(
    vine.object({
        code: vine.string().trim(),
        description: vine.string().trim().escape(),
    })
    
)

export const updateContractStatusValidator = vine.compile(
    vine.object({
        description: vine.string().trim().escape(),
    })
)
