Struct InputState 

pub struct InputState {
    pub cursor_position: usize,
}

State for the input widget

Fields

cursor_position: usize

Cursor position in the input string

Implementations

impl InputState

pub fn new() -> Self

Create a new input state

pub fn calculate_cursor_position( input: &str, cursor_pos: usize, content_width: usize, ) -> (u16, u16)

Calculate cursor position for wrapped text.

content_width is in display cells. Returns (row, col) where col is also in display cells — required because Frame::set_cursor_ position is cell-based, not byte-based. CJK / emoji input previously mispositioned the cursor because the column was returned in bytes.

Uses the shared layout_rows helper so the wrapping decisions match wrap_input_with_prompt exactly (the two would silently drift otherwise — cursor_and_wrap_agree_on_line_structure guards this).
