How to match a String against string literals in Rust?

I'm trying to figure out how to match a String in Rust.

I initially tried matching like this, but I figured out Rust cannot implicitly cast from std::string::String to &str.

fn main() {
    let stringthing = String::from("c");
    match stringthing {
        "a" => println!("0"),
        "b" => println!("1"),
        "c" => println!("2"),
    }
}

This has the error:

error[E0308]: mismatched types
 --> src/main.rs:4:9
  |
4 |         "a" => println!("0"),
  |         ^^^ expected struct `std::string::String`, found reference
  |
  = note: expected type `std::string::String`
             found type `&'static str`

I then tried to construct new String objects, as I could not find a function to cast a String to a &str.

fn main() {
    let stringthing = String::from("c");
    match stringthing {
        String::from("a") => println!("0"),
        String::from("b") => println!("1"),
        String::from("c") => println!("2"),
    }
}

This gave me the following error 3 times:

error[E0164]: `String::from` does not name a tuple variant or a tuple struct
 --> src/main.rs:4:9
  |
4 |         String::from("a") => return 0,
  |         ^^^^^^^^^^^^^^^^^ not a tuple variant or struct

Why We Need To Match Kundli Before Marriage?

When a date is set for marriage between two individuals, perhaps the first thing that the two families do is go for kundli matching by date of birth. Considered one of the most significant and foremost aspects of an arranged Indian marriage, matching Kundli or horoscopes is necessary before two people decide to get hitched, whether they are having a love or arranged marriage. Since matching kundlis can help you to know about any impending problems that await you on the other side of your marriage, experienced astrologers like Dr. Vinay Bajrangi always advise their clients to match horoscopes before marriage to avoid any major mishaps in the future.
Some of the reasons why astrologers recommend using a horoscope match calculator for marriage are as follows –
Compatibility - Kundli matching is important to ascertain compatibility between two individuals in terms of their mental and physical conditions, including mindset, temper, attitude and behaviour. It is considered the basic premise for a successful union. In order to assess that there is a sufficient amount of mutual desirability between the couple, the horoscopes are also analysed for physical attraction, because that is an important tool for a long-lasting relationship.
Finances/Career - Kundli matching is also a way to know about the future prospects of your spouse like career growth, business progress, promotion, financial stability, etc.
Dashas - Sometimes, the negative impact of Dashas (planetary combinations) can ruin your future as a married couple. There is a chance that a person’s horoscope could have Dashas like the ‘Mangal Dasha’ and ‘Shani Dasha’ right since the time they are born, depending upon the stars and the planets’ positions at that time. Such Dashas can create several problems at a later stage of marriage, about which none of the partners can do anything. The process of Kundli matching can help you overcome the negative impact before taking the step towards the marriage altar.
Health – Kundli matching helps you find out about the health prospects of your children, who would be born later in your life. The 8th guna of your Kundli, Nadi, represents childbirth and potential problems that might arise out of it. Therefore, Kundli matching is significant not just for yourself but also for the future generations to come.
Love Marriage – In case of love marriages, matching kundlis or using a horoscope match calculator for marriage is equally important as it helps the couple take care of any possible negative impacts awaiting them in the future. Matching of horoscopes is a sure-shot way to resolve any impending problems for a married couple.

Astrological Combinations for Healthy Marriage

The compatibility of partners as well as their health and finances are all necessary points that should be taken care of before finalizing a match. Birth charts of the two individuals provide all the answers, provided you consult a highly experienced astrologer for the same. In case of malefic effects of the planets, your married life might feel hindrance, which can be avoided with the help of some specific astrological combinations, as given below –

• Mercury and Venus are the two most significant planets in an individual’s horoscope.
• Manglik Yoga, one of the most malefic yogas, is formed in a person’s birth-chart when Mars is in the 1st, 4th, 7th, 8th or the 12th house. This yoga can be nullified only when two persons with similar yoga get married.
• Saturn and Rahu are two other planets that hold great significance in a person’s kundli with respect to his or her marriage prospects.
• When the moon is in the 2nd house of the Venus, it is considered to be highly inauspicious for the bride’s life span.
• The lifespan of both the groom and the bride is similar when the kundli shows a connection between planets Mercury and Venus.
• A groom’s life is at risk when Mercury aspects planets Sun and Rahu. Same is the case when Venus aspects planets Sun, Moon and Rahu.
• An individual whose kundli shows Jupiter aspected by Venus or Rahu aspected by Sun and Moon can expect more than one marriage in their life.

Marriage is a holy union guided by planets and houses in your birth-chart, as well as by a multitude of astrological combinations. Talk to an ace astrologer like Dr. Vinay Bajrangi to know more about kundali matching and its various aspects. What you must understand is that avoiding kundli matching before love or arranged union could keep you unaware of the vagaries of married life, if any. An individual’s nature as well as future is predicted through their kundli and it helps to seek help from a knowledgeable astrologer before making final decision about marriage. Meanwhile, if you want to have your doubts and queries addressed as per the Vedic Astrology, you can connect with Dr. Bajrangi on vinaybajrangi.com or on phone - +91 9278665588 / 9278555588.

What is difference between String and string in C#

Are you confused about System.String and string in C#? What is the difference between String and string in C#? And how to choose between string and System.String? In this article, I am going to show you all the differences between string and System.String in C## with code examples. .

What is the difference between System.String and string in C#?

Basically, there is no difference between string and String in C#. “string” is just an alias of System.String and both are compiled in the same manner. String stands for System.String and it is a .NET Framework type. “string” is an alias in the C## language for System.String. Both of them are compiled to System.String in IL (Intermediate Language), so there is no difference.
