  3. export function is<T>(input: unknown): input is T; // returns boolean
  4. export function assert<T>(input: unknown): T; // throws TypeGuardError
  5. export function validate<T>(input: unknown): IValidation<T>; // detailed
  6. export const customValidators: CustomValidatorMap; // can add custom validators

  8. // JSON
  9. export function application<T>(): IJsonApplication; // JSON schema
  10. export function assertParse<T>(input: string): T; // type safe parser
  11. export function assertStringify<T>(input: T): string; // safe and faster
  12.     // +) isParse, validateParse
