How to Convert Integer to String in Rust ?

Answer

In Rust, you can convert an integer to a string using the to_string() method or by using the format! macro.

✐ Examples

1 Convert Integer to String using to_string()

In this example,

We declare an integer variable named num and assign it a value of 42.
We then use the to_string() method to convert the integer num to a string and store the result in the string variable str_num.
The to_string() method converts the integer to its string representation.
Finally, we print the string representation of the integer to the console.

Rust Program

// Convert Integer to String using to_string()
fn main() {
    let num = 42;
    let str_num = num.to_string();
    println!("String representation of integer: {}", str_num);
}

Output

String representation of integer: 42

2 Convert Negative Integer to String using format! Macro

In this example,

We declare a negative integer variable named negative_num with a value of -10.
We then use the format! macro to convert the negative integer negative_num to a string and store the result in the string variable str_negative_num.
The format! macro provides a convenient way to format strings with variables.
Finally, we print the string representation of the negative integer to the console.

Rust Program

// Convert Negative Integer to String using format! Macro
fn main() {
    let negative_num = -10;
    let str_negative_num = format!("String representation of negative integer: {}", negative_num);
    println!(str_negative_num);
}

Output

String representation of negative integer: -10
