Implementations

impl Navigator

pub fn new(start: NodeId) -> Self

pub fn current(&self) -> &str

pub fn leap( &mut self, dir: Direction, positions: &impl Fn(&str) -> [f32; 2], neighbors: &impl Fn(&str) -> Vec<(NodeId, [f32; 2])>, )

Directional leap. positions maps id->graph position; neighbors returns (id, position) pairs for a node’s edge-connected neighbors.

pub fn sibling( &mut self, delta: i32, positions: &impl Fn(&str) -> [f32; 2], neighbors: &impl Fn(&str) -> Vec<(NodeId, [f32; 2])>, )

Slide to the next (+1) / previous (-1) sibling of the last leap.

pub fn clear_pending(&mut self)

Any non-sibling action clears the sibling context.

pub fn set_current(&mut self, id: NodeId)

Force the current node (e.g. continuity when switching from Focus mode). Does not push history — this is a teleport, not a focus()-style leap.

pub fn back(&mut self)
