Enum SetRenderingNotifierError 

#[non_exhaustive]
#[repr(u8)]
pub enum SetRenderingNotifierError {
    Unsupported = 0,
    AlreadySet = 1,
}

This enum describes the different error scenarios that may occur when the application registers a rendering notifier on a slint::Window.

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.

Unsupported = 0

The rendering backend does not support rendering notifiers.

AlreadySet = 1

There is already a rendering notifier set, multiple notifiers are not supported.

Trait Implementations

impl Clone for SetRenderingNotifierError

fn clone(&self) -> SetRenderingNotifierError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SetRenderingNotifierError

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

Formats the value using the given formatter.

impl Display for SetRenderingNotifierError

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

Formats the value using the given formatter.

impl Error for SetRenderingNotifierError

Available on crate feature std only.

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.
