is it possible to get the memory usage of the running application process or is the one from example retrieving its usage?

use sysinfo::{System, SystemExt};

fn main() {
    let mut sys = System::new_all();
    sys.refresh_all();
    println!("total memory: {} bytes", sys.total_memory());
    println!("used memory : {} bytes", sys.used_memory());
 
}

Yes you can by doing:

use sysinfo::{get_current_pid, ProcessExt, System, SystemExt};

if let Ok(pid) = get_current_pid() {
    let mut system = System::new_all();
    if let Some(p) = system.process(pid) {
        println!("{pid:?} uses {} bytes", p.memory());
    }
}
