Enum PopupPortalError

#[non_exhaustive]
pub enum PopupPortalError {
    DuplicateId,
    UnknownPopup,
    UnknownParent,
    ParentPresentationMismatch,
    ParentNotOpen,
    IdExhausted,
    InvalidBounds,
}

Invalid popup registry operation.

Runtime-handle helpers return these errors and also queue a cloned copy for non-fatal host diagnostics. The enum is non-exhaustive.

Examples

use ailloli_ui_runtime::popup::PopupPortalError;
assert_eq!(PopupPortalError::UnknownPopup.to_string(), "popup identifier is not registered");

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.

DuplicateId

Requested registration ID already exists.

UnknownPopup

Operation addressed an unregistered popup ID.

UnknownParent

A requested parent ID is not registered.

ParentPresentationMismatch

Parent/child owners use different logical window or generation.

ParentNotOpen

A child was opened while its registered parent was closed.

IdExhausted

Checked one-based u64 ID allocation cannot advance.

InvalidBounds

Bounds/anchor contain non-finite edges or negative dimensions.

Trait Implementations

impl Clone for PopupPortalError

fn clone(&self) -> PopupPortalError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PopupPortalError

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

Formats the value using the given formatter.

impl Display for PopupPortalError

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

Formats the value using the given formatter.

impl Error for PopupPortalError

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 PopupPortalError

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