Enum UiError 

#[non_exhaustive]
pub enum UiError {
    Backend(String),
    Render(String),
    Window(String),
    Unsupported(String),
    Layout(String),
    Focus(String),
    Clipboard(String),
    DragDrop(String),
    Other(String),
}

Errors emitted by the OxiUI stack.

This enum is #[non_exhaustive]: downstream match expressions must include a catch-all (_ => …) so new variants can be added without a breaking change.

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.

Backend(String)

A backend (windowing / GPU initialisation) error.

Render(String)

A render-pipeline error.

Window(String)

A window-management error.

Unsupported(String)

The requested feature or backend is not available.

Layout(String)

A layout-engine error (e.g. an unsatisfiable constraint set).

Focus(String)

A focus-management error (e.g. focusing a non-focusable node).

Clipboard(String)

A clipboard access error (e.g. unsupported MIME type, OS denial).

DragDrop(String)

A drag-and-drop protocol error (e.g. rejected payload).

Other(String)

Any other error not covered by the above variants.

Trait Implementations

impl Debug for UiError

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

Formats the value using the given formatter.

impl Display for UiError

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

Formats the value using the given formatter.

impl Error for UiError

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.
