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.

fn is_err(self) -> Self

Verifies that the subject has an err 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.
