Enum PresentationEvent

#[non_exhaustive]
pub enum PresentationEvent {
    AllowCreation,
    Attached,
    Suspend,
    Unavailable(PresentationUnavailableReason),
    Retry,
    Destroy,
}

Input accepted by the pure presentation reducer.

The enum is non-exhaustive. Events carry no native handles and are safe to use in deterministic lifecycle tests.

Examples

use ailloli_ui_runtime::app::{PresentationEvent, PresentationUnavailableReason};
assert_ne!(PresentationEvent::AllowCreation, PresentationEvent::Destroy);
assert_eq!(PresentationEvent::Unavailable(PresentationUnavailableReason::SurfaceLost), PresentationEvent::Unavailable(PresentationUnavailableReason::SurfaceLost));

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

AllowCreation

Authorize transitioning toward native attachment.

Attached

Report successful native attachment and advance generation.

Suspend

Detach/suspend presentation without destroying the logical window.

Unavailable(PresentationUnavailableReason)

Record a non-fatal unavailable state.

Retry

Move an unavailable presentation back to creation-allowed.

Destroy

Enter the terminal destroyed state.

Trait Implementations

impl Clone for PresentationEvent

fn clone(&self) -> PresentationEvent

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PresentationEvent

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

Formats the value using the given formatter.

impl PartialEq for PresentationEvent

fn eq(&self, other: &PresentationEvent) -> 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.
