rustRust borrow trait example

The Rust Borrow trait is a trait that allows a type to borrow data from another type. It is used to provide a safe way to access data without taking ownership of it.

Example code

fn main() {
    let a = String::from("Hello");
    let b = a.borrow();
    println!("{}", b);
}

Output example

Hello

The code above shows an example of using the Borrow trait. The a variable is created with a String value. The b variable is then created by borrowing the data from a using the borrow() method. The println! statement then prints the value of b, which is the same as the value of a.

The Borrow trait is useful for accessing data without taking ownership of it. This allows the data to be used without having to worry about ownership issues.
