rustWorking with Slices in Rust
fn main() {
let n1 = "Onelinerhub".to_string();
println!("length of string: {}",n1.len());
let c1 = &n1[4..9];
println!("{}",c1);
}ctrl + c"Onelinerhub".to_string()declares a String variable a1 | let c1 = &n1[4..9];Creates a new string slice c1 that references a part of the original string n1. The range [4..9] specifies the start and end indices (inclusive) of the substring to be extracted from the original string. The & symbol is used to take a reference to the substring instead of creating a new String object. |
Usage example
fn main() {
let n1 = "Onelinerhub".to_string();
println!("length of string: {}",n1.len());
let c1 = &n1[4..9];
println!("{}",c1);
}output
length of string: 11
