Struct TextInputMethodEdit 

pub struct TextInputMethodEdit {
    pub range: TextSelection,
    pub text: String,
    pub selection: TextSelection,
}

An exact platform edit in the current visible text, including an IME preview. All positions count UTF-16 code units. range is ordered; selection is directed and refers to the resulting text. Empty text is a real deletion.

This is the portable contract of CoreText’s Range/Text/NewSelection request. A client must reject unsupported filtering, normalization or length changes before mutation; it must never acknowledge a different replacement as exact.

Fields

range: TextSelection

text: String

selection: TextSelection

Implementations

impl TextInputMethodEdit

pub fn new( range: TextSelection, text: impl Into<String>, selection: TextSelection, ) -> Self

pub fn apply_to(&self, current: &str) -> Result<String, TextInputMethodError>

Validates both ranges without clamping or splitting a surrogate pair and returns the complete candidate text. No client state is changed.
