rustlang get substring

To get a substring in Rust, you can use the get() method on a string slice. The get() method takes a range of indices and returns a new string slice containing the characters within that range.

Here's an example:

fn main() {
    let s = "Hello, World!";
    let substring = &s[7..12];
    println!("{}", substring);
}

In this example, we have a string s which is "Hello, World!". We use the get() method with the range 7..12 to extract the substring "World". The resulting substring is stored in the variable substring, and then printed to the console.

This will output:

World

You can adjust the range of indices as needed to extract different substrings from the original string. Remember that the range is inclusive on the start index and exclusive on the end index, meaning the character at the end index is not included in the substring.

I hope this helps! Let me know if you have any further questions.
