Enum ImePreeditError

#[non_exhaustive]
pub enum ImePreeditError {
    ReversedSelection,
    SelectionOutOfBounds,
    SelectionNotOnCharBoundary,
}

Invalid UTF-8 byte selection associated with preedit text.

Possible errors distinguish reversed, out-of-bounds, and non-character- boundary selections.

Examples

use ailloli_ui_core::event::{ImePreedit, ImePreeditError};
assert_eq!(ImePreedit::try_new("é", Some((1, 2))).unwrap_err(), ImePreeditError::SelectionNotOnCharBoundary);

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.

ReversedSelection

The start byte index is greater than the end index.

SelectionOutOfBounds

The end byte index exceeds the preedit string length.

SelectionNotOnCharBoundary

At least one byte index splits a UTF-8 encoded scalar value.

Trait Implementations

impl Clone for ImePreeditError

fn clone(&self) -> ImePreeditError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ImePreeditError

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

Formats the value using the given formatter.

impl Display for ImePreeditError

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

Formats the value using the given formatter.

impl Error for ImePreeditError

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 ImePreeditError

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