Borrowing References with &

Snippet

Borrowing References with &

The ampersand symbol creates a reference to a value, allowing you to borrow it without taking ownership. References are immutable by default. String slices are created using the range syntax with &.

snippet.rs
rust
fn main() {
    let value = 42;
    let reference = &value;
    println!("Value: {}, Reference: {}", value, reference);
    
    let text = String::from("Hello Rust");
    let slice = &text[0..5];
    println!("String: {}, Slice: {}", text, slice);
}

Breakdown

let reference = &value;

Borrows value without taking ownership

let slice = &text[0..5];

Creates a string slice from index 0 to 5
