rustHow do I compare a string and a str in Rust?

Comparing strings in Rust is done using the == operator. This operator will compare two strings and return true if they are equal, and false if they are not.

Example

let str1 = "Hello";
let str2 = "World";

println!("{}", str1 == str2);

Output example

false

The == operator compares two strings by comparing each character in the strings. If all characters in the strings are the same, then the strings are equal and the == operator will return true.

In addition to the == operator, Rust also provides the str::eq method which can be used to compare two strings. This method takes two &str references as arguments and returns true if the strings are equal, and false if they are not.

Example

let str1 = "Hello";
let str2 = "World";

println!("{}", str1.eq(&str2));

Output example

false
