Struct Picker 

pub struct Picker {
    pub kind: Kind,
    pub prompt: String,
    pub cursor: usize,
    /* private fields */
}

prompt: String

What has been typed, verbatim.

cursor: usize

Position within hits, not within items.

Implementations

impl Picker

pub fn new(kind: Kind, items: Vec<Item>) -> Self

pub fn is_empty(&self) -> bool

pub fn total(&self) -> usize

pub fn shown(&self) -> usize

pub fn rows(&self) -> impl Iterator<Item = (&Item, &Match)>

The visible entries, best first, each with the match positions that produced it so the renderer can underline the characters that were actually typed.

pub fn selected(&self) -> Option<&Item>

pub fn accept(&self) -> Option<&Target>

The target of the entry under the cursor, if there is one.

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

pub fn backspace(&mut self) -> bool

Delete a character. false when there was nothing to delete, which the caller turns into closing the picker, the way backspace on an empty prompt does everywhere else.

pub fn move_cursor(&mut self, delta: isize)

Move the cursor, clamping rather than wrapping.

Clamping, unlike /, because a picker’s list is right there: running off the bottom and reappearing at the top in a list you can see in full is disorienting, where in a thousand-row table a wrap is the only way to keep going.
