How to remove the first and last characters of a String

There are multiple ways we can do it.

• String slice range This example removes the first and last characters and returns the string. Using a range of a string length starting from 1..string.length-1

fn main() {
    let name = "Welcome";
    let result = &name[1..name.len() - 1];
    println!("{}", result);
}

Output:

elcom

• using split_at with index:

• String.split_at functions is split with string.len()-1

• Next, takes the first string and split it with index=1

• Print the string with index=1 position

fn main() {
    let name = "Welcome";
    let name = name.split_at(name.len() - 1);

    let name = name.0.split_at(1);
    println!("{}", name.1);
}

Output:

elcom
