Struct ImeSurroundingText 

pub struct ImeSurroundingText {
    pub text: String,
    pub anchor: usize,
    pub focus: usize,
}

What an input method may read of the focused field: its text around the selection, for suggestions, autocorrection and word deletion.

Read from the field’s accessibility node, so a field that hides its value from assistive technology (a password) hides it from the keyboard too.

Fields

text: String

anchor: usize

Byte offsets into text.

focus: usize

Implementations

impl ImeSurroundingText

pub const CONTEXT: usize = 2048

Bytes of context kept on each side of the selection.

pub fn from_widget(widget: &dyn Widget) -> Option<ImeSurroundingText>

pub fn around( text: &str, anchor: usize, focus: usize, ) -> Option<ImeSurroundingText>

The selection within text, with up to Self::CONTEXT bytes on each side. None when an offset is not a character boundary.

Trait Implementations

impl Clone for ImeSurroundingText

fn clone(&self) -> ImeSurroundingText

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ImeSurroundingText

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

Formats the value using the given formatter.

impl Default for ImeSurroundingText

fn default() -> ImeSurroundingText

Returns the “default value” for a type.

impl PartialEq for ImeSurroundingText

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