Struct Jump 

pub struct Jump { /* private fields */ }

The jump picker’s state: the query line (an editable tui_input::Input), the candidate set (built once on open), the ranked results, and view state (selection + scroll).

Implementations

impl Jump

pub fn open(tree: &Tree) -> Self

Open a picker over every node in the current tree view, ranked for the empty query (i.e. all candidates in tree order).

pub fn handle_key(&mut self, key: Key) -> JumpOutcome

Route a key to the picker. Result-navigation, accept, and cancel keys are handled here; everything else is offered to the query line’s tui_input editor. All of these are fixed (not the user’s configurable keymap — see the v1 boundary in app.rs).

pub fn query(&self) -> &str

pub fn visual_cursor(&self) -> usize

The caret’s display column within the query text (accounts for wide characters); pairs with Jump::visual_scroll for rendering.

pub fn visual_scroll(&self, width: usize) -> usize

The horizontal scroll offset (in display columns) that keeps the caret visible in a query field width columns wide.

pub fn results(&self) -> &[Match]

pub fn selected(&self) -> usize

pub fn scroll(&self) -> usize

pub fn matched(&self) -> usize

Number of candidates matched by the current query.

pub fn total(&self) -> usize

Total number of candidates in the current tree view.

pub fn path(&self, id: NodeId) -> &str

The path text for a node id (what was matched, and what is displayed).

pub fn set_viewport(&mut self, rows: usize)

Tell the picker how many result rows the viewport can show, keeping the selection visible. Called by the renderer each frame.
