Struct Update

pub struct Update<Ef, Ev> {
    pub effects: Vec<Ef>,
    pub events: Vec<Ev>,
}

Update test helper holds the result of running an app update using AppTester::update or resolving a request with AppTester::resolve.

Fields

effects: Vec<Ef>

Effects requested from the update run

events: Vec<Ev>

Events dispatched from the update run

Implementations

impl<Ef, Ev> Update<Ef, Ev>

pub fn into_effects(self) -> impl Iterator<Item = Ef>

pub fn effects(&self) -> impl Iterator<Item = &Ef>

pub fn effects_mut(&mut self) -> impl Iterator<Item = &mut Ef>

pub fn expect_one_effect(self) -> Ef

Assert that the update contains exactly one effect and zero events, and return the effect

Panics

Panics if the update contains more than one effect or any events.

pub fn expect_one_event(self) -> Ev

Assert that the update contains exactly one event and zero effects, and return the event

Panics

Panics if the update contains more than one event or any effects.

pub fn assert_empty(self)

Assert that the update contains no effects or events

Panics

Panics if the update contains any effects or events.

pub fn take_effects<P>(&mut self, predicate: P) -> VecDeque<Ef>

where P: FnMut(&Ef) -> bool,

Take effects matching the predicate out of the Update and return them, mutating the Update

pub fn take_effects_partitioned_by<P>( &mut self, predicate: P, ) -> (VecDeque<Ef>, VecDeque<Ef>)

where P: FnMut(&Ef) -> bool,

Take all of the effects out of the Update and split them into those matching predicate and the rest

Trait Implementations

impl<Ef: Debug, Ev: Debug> Debug for Update<Ef, Ev>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
