Struct TextInputMethodComposition 

pub struct TextInputMethodComposition(/* private fields */);

A platform composition bound to one connection and one accepted client state. Clones refer to the same session. Late callbacks fail after reset, focus handoff, external edits, or a newer native composition.

Implementations

impl TextInputMethodComposition

pub fn is_current(&self) -> bool

pub fn update( &self, text: &str, cursor: Option<i32>, ) -> Result<(), TextInputMethodError>

pub fn apply_edit( &self, edit: &TextInputMethodEdit, ) -> Result<bool, TextInputMethodError>

Applies the platform’s delta to the current preview without committing history. The resulting selection is part of this operation.

pub fn select_exact( &self, selection: TextSelection, ) -> Result<(), TextInputMethodError>

pub fn complete(&self, timestamp: u64) -> Result<bool, TextInputMethodError>

Commits exactly the accepted preview, including empty deletions and arbitrary directed selection, as one undo transaction.

pub fn commit( &self, text: &str, timestamp: u64, ) -> Result<bool, TextInputMethodError>

pub fn cancel(&self) -> Result<bool, TextInputMethodError>
