Trait AssertOptionValue 

pub trait AssertOptionValue<'a, T, R> {
    // Required method
    fn some(self) -> Spec<'a, T, R>;
}

Assert the value of an option by mapping the subject.

If the option is none, the assertion fails.

Examples

use asserting::prelude::*;

let subject: Option<Vec<usize>> = Some(vec![1, 2, 3]);
assert_that!(subject).some().contains_exactly([1, 2, 3]);

let subject: Option<&str> = Some("ullamco cupiditat diam hendrerit");
assert_that!(subject).some().is_not_empty();

Required Methods

fn some(self) -> Spec<'a, T, R>

Maps the subject to the option’s value if it has some. Otherwise, this assertion fails.

Examples

use asserting::prelude::*;

let subject: Option<Vec<usize>> = Some(vec![1, 2, 3]);
assert_that!(subject).some().contains_exactly([1, 2, 3]);

let subject: Option<&str> = Some("ullamco cupiditat diam hendrerit");
assert_that!(subject).some().is_not_empty();
