Function clap_num::si_number_range

pub fn si_number_range<T: Ord + PartialOrd + Display>(
    s: &str, 
    min: T, 
    max: T
) -> Result<T, String> where
    <T as TryFrom<u128>>::Error: Display,
    <T as FromStr>::Err: Display,
    T: CheckedAdd,
    T: CheckedMul,
    T: CheckedSub,
    T: FromStr,
    T: PartialOrd,
    T: TryFrom<u128>,
    T: Zero, 

Validate a signed or unsigned integer value with a metric prefix within a range.

This effectively combines si_number and number_range, see the documentation for those functions for details.

Example

This extends the example in si_number, and only allows a range of resistances from 1k to 999.999k.

use clap::Clap;
use clap_num::si_number_range;

fn kilo(s: &str) -> Result<u32, String> {
    si_number_range(s, 1_000, 999_999)
}

#[derive(Clap)]
struct Args {
    #[clap(short, long, parse(try_from_str=kilo))]
    resistance: u32,
}
