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

pub fn expect_one_event(self) -> Ev

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

pub fn assert_empty(self)

Assert that the update contains no 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.
