Struct PresentationReduction

pub struct PresentationReduction {
    pub state: PresentationState,
    pub generation: PresentationGeneration,
    pub generation_changed: bool,
}

Result of one pure lifecycle reduction.

generation_changed is true only for successful attachment and always equals generation != the reducer’s input generation.

Examples

use ailloli_ui_runtime::app::{reduce_presentation, PresentationEvent, PresentationGeneration, PresentationState};
let reduced = reduce_presentation(PresentationState::Declared, PresentationGeneration::INITIAL, PresentationEvent::AllowCreation)?;
assert_eq!(reduced.state, PresentationState::CreationAllowed);
assert!(!reduced.generation_changed);

Fields

state: PresentationState

State after applying the event.

generation: PresentationGeneration

Generation after applying the event.

generation_changed: bool

Whether generation advanced during this reduction.

Trait Implementations

impl Clone for PresentationReduction

fn clone(&self) -> PresentationReduction

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PresentationReduction

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

Formats the value using the given formatter.

impl PartialEq for PresentationReduction

fn eq(&self, other: &PresentationReduction) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
