Struct overflow_error::DivByZero

pub struct DivByZero;

Division could not be performed due to division by zero.

Methods

impl DivByZero

pub fn val<T>(self, val: T) -> DivValueByZero<T>

Adds a payload to this error, representing the left-hand-side of the division.

Examples

use overflow_error::*;

fn checked_div(a: u32, b: u32) -> Result<u32, DivValueByZero<u32>>
{
    if b == 0 {
        Err(DivByZero.val(a))
    } else {
        Ok(a / b)
    }
}

let result = checked_div(1, 0);
assert!(*result.unwrap_err().as_inner() == 1);

pub fn as_str(&self) -> &'static str

String representing the error.

Examples

use overflow_error::*;
assert!(DivByZero.as_str() == "division by zero");
