Enum druid::text::ImeInvalidation

#[non_exhaustive]
pub enum ImeInvalidation {
    SelectionChanged,
    LayoutChanged,
    Reset,
}

An event representing an application-initiated change in InputHandler state.

When we change state that may have previously been retrieved from an InputHandler, we notify the platform so that it can invalidate any data if necessary.

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.

SelectionChanged

Indicates the value returned by InputHandler::selection may have changed.

LayoutChanged

Indicates the values returned by one or more of these methods may have changed:

• InputHandler::hit_test_point
• InputHandler::line_range
• InputHandler::bounding_box
• InputHandler::slice_bounding_box

Reset

Indicates any value returned from any InputHandler method may have changed.

Trait Implementations

impl Clone for Event

fn clone(&self) -> Event

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Event

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

Formats the value using the given formatter.

impl Hash for Event

fn hash<__H>(&self, state: &mut __H)where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<Event> for Event

fn eq(&self, other: &Event) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
