# Checking conditions with the `IsNoneOr` trait

The provided `is_none_or` method is a mirror to the core library's `is_some_and` method.
It returns `true` if the option is a [`None`] or the option is [`Some`] and the value
inside of it matches a predicate.

# Examples

```rs
use is_none_or::IsNoneOr;

let x: Option<u32> = Some(2);
assert_eq!(x.is_none_or(|x| x > 1), true);

let x: Option<u32> = Some(0);
assert_eq!(x.is_none_or(|x| x > 1), false);

let x: Option<u32> = None;
assert_eq!(x.is_none_or(|x| x > 1), true);
```
