Trait AssertOption

pub trait AssertOption {
    // Required methods
    fn is_some(self) -> Self;
    fn is_none(self) -> Self;
}

Assert whether a subject of the Option type holds some value or has none.

Examples

use asserting::prelude::*;

let subject = Some("nisl possim nobis non".to_string());
assert_that!(subject).is_some();

#[derive(Debug)]
struct MyType;

let subject: Option<MyType> = None;
assert_that!(subject).is_none();

Required Methods

fn is_some(self) -> Self

Verifies that the subject has some value.

fn is_none(self) -> Self

Verifies that the subject has no value.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
