Enum PresentationTransitionError

pub enum PresentationTransitionError {
    Destroyed,
    AttachmentNotAllowed,
    GenerationExhausted,
    RetryNotAllowed,
}

Invalid presentation lifecycle transition.

Errors carry no native-resource detail and leave PresentationLifecycle unchanged when returned through its PresentationLifecycle::apply method.

Examples

use ailloli_ui_runtime::app::PresentationTransitionError;
assert_eq!(PresentationTransitionError::AttachmentNotAllowed.to_string(), "a presentation can only attach after creation is allowed");

Variants

Destroyed

The presentation has already reached its terminal destroyed state.

AttachmentNotAllowed

Attachment was requested before creation became allowed.

GenerationExhausted

Incrementing the u64 presentation generation would overflow.

RetryNotAllowed

Retry was requested from a state other than unavailable.

Trait Implementations

impl Clone for PresentationTransitionError

fn clone(&self) -> PresentationTransitionError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PresentationTransitionError

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

Formats the value using the given formatter.

impl Display for PresentationTransitionError

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

Formats the value using the given formatter.

impl Error for PresentationTransitionError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for PresentationTransitionError

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