Trait OkPredicateAssertion 

pub trait OkPredicateAssertion<T> {
    // Required methods
    fn should_be_ok_and_satisfy<F: Fn(&T) -> bool>(&self, predicate: F) -> &Self;
    fn should_be_ok_and_not_satisfy<F: Fn(&T) -> bool>(
        &self,
        predicate: F,
    ) -> &Self;
}

OkPredicateAssertion enables assertions about whether the Result value is both Ok and that the contained value meets or doesn’t meet certain conditions defined by a predicate.

Required Methods

fn should_be_ok_and_satisfy<F: Fn(&T) -> bool>(&self, predicate: F) -> &Self

• Asserts that the Result value is Ok and satisfies the given predicate.
• Returns a reference to self for fluent chaining.
• Panics if the assertion fails.

Example

use clearcheck::assertions::result::predicate::OkPredicateAssertion;

let value: Result<i32, &str> = Ok(1000);
value.should_be_ok_and_satisfy(|value| value > &50);

fn should_be_ok_and_not_satisfy<F: Fn(&T) -> bool>(&self, predicate: F) -> &Self

• Asserts that the Result value is Ok and does not satisfy the given predicate.
• Returns a reference to self for fluent chaining.
• Panics if the assertion fails.

Example

use clearcheck::assertions::result::predicate::OkPredicateAssertion;

let value: Result<i32, &str> = Ok(100);
value.should_be_ok_and_not_satisfy(|value| value > &500);

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
