Struct PickerState 

pub struct PickerState {
    pub filter: String,
    /* private fields */
}

The list and where the cursor is in it. Owns the narrowing; the caller owns what choosing means.

Fields

filter: String

Implementations

impl PickerState

pub fn new(items: Vec<String>) -> Self

pub fn items(&self) -> &[String]

Every item, whatever the filter admits.

pub fn filtered(&self) -> Vec<(usize, &str)>

The items the filter admits, with their original indices: the one it names first, then those it starts, then the rest, each in list order.

pub fn visible_selection(&self) -> usize

Where the cursor sits among the visible items; 0 when the item it was on has been filtered away.

pub fn selected_original(&self) -> Option<usize>

The selected item’s original index, or None when the filter admits nothing.

pub fn select_original(&mut self, index: usize)

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

pub fn backspace(&mut self)

pub fn clear_filter(&mut self)

pub fn filter_key(&mut self, c: char, mods: KeyModifiers)

One typed character, with its modifiers: plain characters narrow, Ctrl+W drops a word, Ctrl+U clears, and any other chord is a chord — never a letter typed into the filter.

pub fn delete_word(&mut self)

Ctrl+W: drop the word before the cursor, readline-style. The filter is append-only, so the cursor is always the end.

pub fn move_up(&mut self)

pub fn move_down(&mut self)
