Trait EffectAssertions 

pub trait EffectAssertions<E> {
    // Required methods
    fn effects_empty(&self);
    fn effects_not_empty(&self);
    fn effects_count(&self, n: usize);
    fn effects_any_matches<F: Fn(&E) -> bool>(&self, f: F);
    fn effects_first_matches<F: Fn(&E) -> bool>(&self, f: F);
    fn effects_all_match<F: Fn(&E) -> bool>(&self, f: F);
    fn effects_none_match<F: Fn(&E) -> bool>(&self, f: F);
}

Fluent assertions for effect vectors.

Method names are prefixed with effects_ to avoid conflicts with ActionAssertions when both traits are in scope.

Example

use tui_dispatch::testing::EffectAssertions;

let effects = harness.drain_effects();
effects.effects_count(1);
effects.effects_first_matches(|e| matches!(e, Effect::FetchWeather { .. }));

Required Methods

fn effects_empty(&self)

Assert the effect vector is empty.

fn effects_not_empty(&self)

Assert the effect vector is not empty.

fn effects_count(&self, n: usize)

Assert the effect vector has exactly n elements.

fn effects_any_matches<F: Fn(&E) -> bool>(&self, f: F)

Assert any effect matches the predicate.

fn effects_first_matches<F: Fn(&E) -> bool>(&self, f: F)

Assert the first effect matches the predicate.

fn effects_all_match<F: Fn(&E) -> bool>(&self, f: F)

Assert all effects match the predicate.

fn effects_none_match<F: Fn(&E) -> bool>(&self, f: F)

Assert no effects match the predicate.

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.
