v0.1.0

0.1.0 (2020-12-02)

New features

• Adds point_to_segment_distance for calculating the shortest distance from a
  point to a given line segment.
• Adds change_unit and clone_with_unit methods that allow an existing
  ruler's unit to be changed, and distance_unit to get the current unit used
  by the ruler.

Feature changes

• along now returns an Option<Point<f64>> to support the case where the
  provided LineString is empty without a panic.
• area now accepts a single Polygon instead of a slice. The given polygon's
  interiors are subtracted from the area instead of the other elements in the
  polygon slice.
• buffer_point, buffer_bbox and inside_bbox APIs now take points and
  rectangles by reference instead of by value. Additionally, they accept a
  custom Rect type, not geo_types::Rect, due to that type's invariants
  causing problems when drawing a bounding box that goes over the international
  date line. A convenience From trait is implemented.
• point_on_line also now returns an Option<PointOnLine<f64>> to support the
  case where an empty LineString is provided.
• Removed From<(Point<T>, usize, T)> for PointOnLine<T> trait implementation,
  the point_on_line method now directly uses the constructor, which is saner.

Bug fixes

• buffer_bbox now returns correct results for a box crossing the international
  date line.

Misc

• Adds test coverage for all methods based on mapbox/cheap-ruler and
  mapbox/cheap-ruler-cpp implementations.
• Adds the project to github workflows with cargo clippy and fmt as additional
  test steps.
• Use lat and lng methods on geo_types::Point instead of x and y for
  context.
