Function fraction::division::write_digit

pub fn write_digit(
    writeable: &mut dyn Write,
    digit: u8,
) -> Result<bool, DivisionError>

A helper function to use in conjunction with divide_to_callback

divide_to_callback passes digits to its callback, this function can be used to write digits (and dots) into the writeable buffer after your callback performs its side-effects.

Examples

use fraction::division::{divide_to_callback, write_digit};

let mut result = String::new();
let mut length = 0;

// calculate 7/4, which is 1.75
divide_to_callback(7, 4, 2, false, |d| { length += 1; write_digit(&mut result, d) }).ok();

assert_eq!(&result, "1.75");
assert_eq!(length, result.len());
