Struct overflow_error::OverflowedValue

pub struct OverflowedValue<T>(_);

[Overflowed] with a payload.

Methods

impl<T> OverflowedValue<T>

pub fn ignore_inner(&self) -> Overflowed

Ignores the overflowed value.

Examples

use overflow_error::Overflowed;
assert!(Overflowed.val(5).ignore_inner() == Overflowed);

pub fn into_inner(self) -> T

Returns the overflowed value.

Examples

use overflow_error::Overflowed;
assert!(Overflowed.val(5).into_inner() == 5);

pub fn as_inner(&self) -> &T

References the overflowed value.

Examples

use overflow_error::Overflowed;
assert!(*Overflowed.val(5).as_inner() == 5);

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

Applies a function to the overflowed value.

Examples

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