Struct TextInputState 

pub struct TextInputState {
    pub value: String,
    pub cursor: usize,
    pub selection_anchor: Option<usize>,
}

Helper struct for managing text input state.

This provides a convenient way to manage the value, cursor position, selection, and handle common editing operations.

Fields

value: String

The current text value.

cursor: usize

Cursor position (character index).

selection_anchor: Option<usize>

Selection anchor (where selection started). None = no selection.

Implementations

impl TextInputState

pub fn new() -> Self

Create a new empty state.

pub fn with_value(value: impl Into<String>) -> Self

Create a new state with initial value.

pub fn insert(&mut self, c: char)

Insert a character at the cursor position. If there’s a selection, it’s deleted first.

pub fn insert_str(&mut self, s: &str)

Insert a string at the cursor position. If there’s a selection, it’s deleted first.

pub fn backspace(&mut self) -> bool

Delete the character before the cursor (backspace). If there’s a selection, deletes the selection instead.

pub fn delete(&mut self) -> bool

Delete the character at the cursor position (delete). If there’s a selection, deletes the selection instead.

pub fn move_left(&mut self) -> bool

Move cursor left (clears selection).

pub fn move_right(&mut self) -> bool

Move cursor right (clears selection).

pub fn move_home(&mut self)

Move cursor to the start (clears selection).

pub fn move_end(&mut self)

Move cursor to the end (clears selection).

pub fn clear(&mut self)

Clear the input.

pub fn set_value(&mut self, value: impl Into<String>)

Set the value and move cursor to end.

pub fn value(&self) -> &str

Get the current value.

pub fn is_empty(&self) -> bool

Check if the input is empty.

pub fn has_selection(&self) -> bool

Check if there’s an active selection.

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

Get selection range (start, end) where start <= end.

pub fn selected_text(&self) -> Option<&str>

Get the selected text.

pub fn clear_selection(&mut self)

Clear the selection without deleting text.

pub fn delete_selection(&mut self) -> Option<String>

Delete the selected text and return it.

pub fn select_all(&mut self)

Select all text.

pub fn select_left(&mut self) -> bool

Move cursor left with selection (shift+left).

pub fn select_right(&mut self) -> bool

Move cursor right with selection (shift+right).

pub fn select_to_home(&mut self)

Select to beginning (shift+home).

pub fn select_to_end(&mut self)

Select to end (shift+end).

pub fn to_props(&self) -> TextInputProps

Convert to props for rendering.

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

Performs copy-assignment from source.

impl Debug for TextInputState

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

Formats the value using the given formatter.

impl Default for TextInputState

fn default() -> TextInputState

Returns the “default value” for a type.
