Crate nonneg_float

A generic wrapper for non-negative floating point values.

Ensures that values are >= 0 and finite, providing safe construction methods and a convenient macro.

Supports any float type implementing num_traits::Float.

Examples

use nonneg_float::{NonNegative, nonneg};

let zero = NonNegative::<f64>::zero();
let val = NonNegative::try_new(3.14).unwrap();
let macro_val = nonneg!(5.0f64).unwrap();

assert_eq!(zero.get(), 0.0);
assert_eq!(val.get(), 3.14);
assert_eq!(macro_val.get(), 5.0);
