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

// JSON
export function application<T>(): IJsonApplication; // JSON schema
export function assertParse<T>(input: string): T; // type safe parser
export function assertStringify<T>(input: T): string; // safe and faster
    // +) isParse, validateParse 
    // +) stringify, isStringify, validateStringify

// MISC
export function random<T>(g?: Partial<IRandomGenerator>): Primitive<T>;
