export const trytm = async <T>(
    promise: Promise<T>,
): Promise<TryResult<T>> => {
    const getResult = (data: T | null, error: Error | null) => ({ 
        data, 
        error,  
        [Symbol.iterator]: function* () {
            yield this.data;
            yield this.error;
        }
    })
    try {
        const data = await promise;
        return getResult(data, null);
    } catch (throwable) {
        if (throwable instanceof Error) {
            return getResult(null, throwable);
        }
        
        throw throwable;
    }
