Macro assert_pos_relative_eq 

macro_rules! assert_pos_relative_eq {
    ($left:expr, $right:expr, $epsilon:expr) => { ... };
}

Asserts that two Positive values are relatively equal within a given epsilon.

This macro compares two Positive values and checks if their relative difference is within the specified epsilon. It handles cases where one or both values are zero, ensuring that the non-zero value is less than or equal to epsilon.

Examples

use positive::Positive;
use positive::{assert_pos_relative_eq, pos_or_panic};

let a = pos_or_panic!(1.0);
let b = pos_or_panic!(1.0001);
let epsilon = pos_or_panic!(0.001);
assert_pos_relative_eq!(a, b, epsilon); // Passes

use positive::{assert_pos_relative_eq, pos_or_panic};

let c = pos_or_panic!(1.0);
let d = pos_or_panic!(2.0);
let epsilon = pos_or_panic!(0.001);
assert_pos_relative_eq!(c, d, epsilon); // Panics

Panics

This macro panics if the relative difference between the two values is greater than the specified epsilon, or if one value is zero and the other is greater than epsilon. The panic message includes the values being compared, the expected relative difference, and the actual relative difference.
