Struct TrackIntervals 

struct TrackIntervals {
    intervals: SmallVec<[OccupiedInterval; 2]>,
}

The occupied cells of a single track, stored as a sorted list of disjoint intervals in OriginZero line coordinates. Gaps between intervals are unoccupied. Touching intervals with the same state are merged.

Fields

intervals: SmallVec<[OccupiedInterval; 2]>

The sorted, disjoint list of occupied intervals within the track

Implementations

impl TrackIntervals

fn is_empty(&self) -> bool

Whether the track contains any occupied cells

fn state_at(&self, coordinate: i16) -> CellOccupancyState

The occupancy state of the cell whose start line is at coordinate

fn paint(&mut self, range: Range<i16>, state: CellOccupancyState)

Set the cells covered by range to state, overwriting the state of any already-occupied cells within the range (matching the overwrite semantics of a dense matrix of cells)

fn collision_extent(&self, range: &Range<i16>, reversed: bool) -> Option<i16>

Find the extent of the occupied interval which an auto-placement search along the track would collide with last: the end of the last overlapping interval when searching forwards, or the start of the first overlapping interval when searching backwards (reversed == true). Returns the extremal occupied cell of that interval (which may lie outside range: every search position before the returned extent also collides with the interval), or None if the range is entirely unoccupied.

fn first_of_state(&self, state: CellOccupancyState) -> Option<i16>

The start line of the first (lowest coordinate) cell with the specified state, if any

fn last_of_state(&self, state: CellOccupancyState) -> Option<i16>

The start line of the last (highest coordinate) cell with the specified state, if any
