Struct overflow_error::CannotDivValue

pub struct CannotDivValue<T>(_);

[CannotDiv] with a payload.

Methods

impl<T> CannotDivValue<T>

pub fn ignore_inner(&self) -> CannotDiv

Ignores the would-be-divided value.

Examples

use overflow_error::*;
assert!(
    CannotDiv::ByZero.val(5).ignore_inner()
    == CannotDiv::ByZero
);
assert!(
    CannotDiv::WouldOverflow.val(5).ignore_inner()
    == CannotDiv::WouldOverflow
);

pub fn into_inner(self) -> T

Returns the would-be-divided value.

Examples

use overflow_error::*;
assert!(CannotDiv::ByZero.val(5).into_inner() == 5);
assert!(CannotDiv::WouldOverflow.val(5).into_inner() == 5);

pub fn as_inner(&self) -> &T

References the would-be-divided value.

Examples

use overflow_error::*;
assert!(*CannotDiv::ByZero.val(5).as_inner() == 5);
assert!(*CannotDiv::WouldOverflow.val(5).as_inner() == 5);

pub fn map<U, F>(self, f: F) -> CannotDivValue<U> where
    F: FnOnce(T) -> U, 

Applies a function to the would-be-divided value.

Examples

use overflow_error::*;
assert!(*CannotDiv::ByZero.val(5).map(i32::wrapping_neg).as_inner() == -5);
assert!(*CannotDiv::WouldOverflow.val(5).map(i32::wrapping_neg).as_inner() == -5);
