type TFormHookPerformValidation<formValuesT> = (params: {
  formValues: formValuesT,
  debugName?: string,
}) => {
  isPassing: boolean,
  fieldErrors: Record<string, unknown>,
  formError: string,
}

const performValidation: TFormHookPerformValidation = params => {

  // Do something based on params and return
  return {
    isPassing: true,
    fieldErrors: {},
    formError: ''
  }
}

TFormHookPerformValidation expects 1 generics, but when defining functions the type assignment will come first before the generics setup, so how can we accept generics in performValidation function and pass it to TFormHookPerformValidation.

Note: I can use Parameters and ReturnType but I would like to know if it’s possible to assign the function type itself.
