Trait AssertResult 

pub trait AssertResult {
    // Required methods
    fn is_ok(self) -> Self;
    fn is_err(self) -> Self;
}

Assert whether a subject of the Result type holds some value or an error.

Examples

use asserting::prelude::*;

let subject: Result<f64, String> = Ok(-3.14);
assert_that!(subject).is_ok();

let subject: Result<(), String> = Err("consequat sanctus ea exercitation".to_string());
assert_that!(subject).is_err();

Required Methods

fn is_ok(self) -> Self

Verifies that the subject has an ok value.

Examples

use asserting::prelude::*;

let subject: Result<f64, String> = Ok(-3.14);
assert_that!(subject).is_ok();

fn is_err(self) -> Self

Verifies that the subject has an err value.

Examples

use asserting::prelude::*;

let subject: Result<(), String> = Err("consequat sanctus ea exercitation".to_string());
assert_that!(subject).is_err();

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.
