Struct WindowTextInputSnapshot 

pub struct WindowTextInputSnapshot {
    pub focus_is_text_input: bool,
    pub is_composing: bool,
    pub text_len_utf16: u32,
    pub selection_utf16: Option<(u32, u32)>,
    pub marked_utf16: Option<(u32, u32)>,
    pub ime_cursor_area: Option<Rect>,
    pub surrounding_text: Option<WindowImeSurroundingText>,
}

Window-scoped platform text-input snapshots published by the UI runtime.

This is a data-only integration seam for platform/runner layers that need to interop with editor-grade text input (IME, accessibility).

Indices are expressed in UTF-16 code units over the widget’s composed view: base buffer text with the active IME preedit spliced at the caret.

Fields

focus_is_text_input: bool

is_composing: bool

text_len_utf16: u32

Total length (UTF-16 code units) of the composed view.

selection_utf16: Option<(u32, u32)>

Anchor/focus selection offsets in UTF-16 code units (composed view).

marked_utf16: Option<(u32, u32)>

Marked (preedit) range in UTF-16 code units (composed view).

ime_cursor_area: Option<Rect>

Best-effort IME cursor area in window logical coordinates.

On Windows/winit this is the primary hook for positioning the candidate window.

surrounding_text: Option<WindowImeSurroundingText>

Best-effort surrounding text excerpt for IME backends that support it.

Trait Implementations

impl Clone for WindowTextInputSnapshot

fn clone(&self) -> WindowTextInputSnapshot

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WindowTextInputSnapshot

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

Formats the value using the given formatter.

impl Default for WindowTextInputSnapshot

fn default() -> WindowTextInputSnapshot

Returns the “default value” for a type.

impl PartialEq for WindowTextInputSnapshot

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