Examples

use color_eyre::{Result, eyre::ensure};

fn get_positive() -> Result<()> {
    check_positive_double!(1.0_f64);
    Ok(())
}
fn get_zero() -> Result<()> {
    check_positive_double!(2.2_f64, 0.0_f64, 1.0_f64);
    Ok(())
}

fn main() {
    let succeeds = get_positive();
    let errors = get_zero();
    assert!(succeeds.is_ok());
    assert!(errors.is_err());
