Generate random numbers ranging from negative infinity Rust

How can I generate a random number ranging from negative infinity to 2.0?

Here is a snip of the code which I wrote to achieve it:

  let neginf =  std::f64::NEG_INFINITY;
  let mut rng = rand::thread_rng();
  let normal = Uniform::new(neginf, 2.0);
  let v = normal.sample(&mut rng);

The error message which I get is:

thread 'main' panicked at 'Uniform::new: range overflow'

I'll be grateful for any hints.
