Struct TextFieldValue 

pub struct TextFieldValue {
    pub annotated_string: AnnotatedString,
    pub selection: TextRange,
    pub composition: Option<TextRange>,
}

Snapshot of a text field’s editing state including text, selection, and IME composition range. Corresponds to Compose’s TextFieldValue.

Fields

annotated_string: AnnotatedString

The annotated text. Plain text is accessible via text() or annotated_string.text.

selection: TextRange

Selection range in byte offsets. Collapsed range (start == end) = cursor.

composition: Option<TextRange>

Active IME composition range in byte offsets, or None.

Implementations

impl TextFieldValue

pub fn new(text: impl Into<String>) -> Self

Create from plain text (no annotations).

pub fn from_annotated(annotated: AnnotatedString) -> Self

Create from an AnnotatedString preserving all annotations.

pub fn text(&self) -> &str

Convenience: plain text content (delegates to annotated_string.text).

pub fn with_selection(self, start: usize, end: usize) -> Self

pub fn get_text_before_selection(&self, max_chars: usize) -> AnnotatedString

pub fn get_text_after_selection(&self, max_chars: usize) -> AnnotatedString

pub fn get_selected_text(&self) -> AnnotatedString

pub fn copy(&self, annotated_string: AnnotatedString) -> Self

Returns a copy with the given annotated string.

pub fn copy_text(&self, text: String) -> Self

Returns a copy with the given plain text.

Trait Implementations

impl Clone for TextFieldValue

fn clone(&self) -> TextFieldValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TextFieldValue

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

Formats the value using the given formatter.

impl PartialEq for TextFieldValue

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