Struct Velocity 

pub struct Velocity { /* private fields */ }

Velocity along the shaft axis (signed: +up, -down).

Display

Formats as a compact speed string:

let vel = Velocity::from(1.2);
assert_eq!(format!("{vel}"), "1.20m/s");
let stopped = Velocity::from(0.0);
assert_eq!(format!("{stopped}"), "0.00m/s");
