rustHow do I compare strings in Rust?

Strings in Rust can be compared using the cmp() method. This method returns an Ordering enum which can be used to determine if two strings are equal, one is greater than the other, or one is less than the other.

Example

let string1 = "Hello";
let string2 = "World";

let comparison = string1.cmp(&string2);

println!("{:?}", comparison);

Code explanation

• let string1 = "Hello";: This creates a string variable called string1 and assigns it the value "Hello".
• let string2 = "World";: This creates a string variable called string2 and assigns it the value "World".
• let comparison = string1.cmp(&string2);: This calls the cmp() method on string1 and passes string2 as an argument. This returns an Ordering enum which is assigned to the comparison variable.
• println!("{:?}", comparison);: This prints the value of the comparison variable to the console.
