    pub buffer: TextBuffer,
    pub caret: usize,
    pub anchor: usize,
    pub history: TextEditHistory,
    pub preedit: Option<TextPreeditState>,

Fields

buffer: TextBuffer

caret: usize

anchor: usize

history: TextEditHistory

preedit: Option<TextPreeditState>

platform_composing: Option<TextRange>

Composing range when a platform adapter synchronizes a complete value whose composing text is already present in buffer.

composition_base: Option<TextEditingValue>

pending_model_sync: bool

last_model_text: String

Last semantic model value observed for this input.

While a local edit is pending, this lets the input distinguish “the app has not observed the edit yet” from “the app observed it and produced a transformed value”.

last_dispatched_cursor: Option<(usize, usize)>

Last cursor position that was dispatched as a CursorChanged action. Used to deduplicate dispatches and prevent unnecessary model updates that could cause extra rebuild cycles.

affordances: TextInputAffordanceState

Implementations

impl TextEditState

pub fn editing_value(&self) -> TextEditingValue

Returns the complete authoritative value for this editing session.

pub fn apply_editing_value(&mut self, value: TextEditingValue) -> String

Atomically commits a complete value while recording one undo entry.

pub fn sync_composing_value(&mut self, value: TextEditingValue)

Synchronizes an in-progress platform composition without creating an undo entry; the eventual composition commit is the atomic history step.

pub fn snapshot(&self) -> TextRestorationSnapshot

pub fn restore_snapshot(&mut self, snapshot: &TextRestorationSnapshot)

pub fn set_history_capacity(&mut self, capacity: usize)

pub fn committed_text(&self) -> String

pub fn sync_from_model(&mut self, semantic_value: &str)

pub fn selection_range(&self) -> (usize, usize)

pub fn clear_preedit(&mut self)

pub fn set_preedit(&mut self, text: String, cursor: Option<(usize, usize)>)

pub fn display_text(&self) -> (String, Option<(usize, usize)>)

pub fn display_preedit_cursor_range(&self) -> Option<(usize, usize)>

pub fn apply_edit( &mut self, range: Range<usize>, new_text: &str, next_caret: usize, next_anchor: usize, ) -> String

pub fn undo(&mut self) -> Option<(String, usize, usize)>

pub fn redo(&mut self) -> Option<(String, usize, usize)>

Trait Implementations

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

Performs copy-assignment from source.

impl Debug for TextEditState

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

impl Default for TextEditState

fn default() -> Self

Returns the “default value” for a type.
