Changelog

Sourced from savvy's changelog.

[v0.5.0] (2024-04-05)

Breaking change

• To support enum properly (the details follow), now savvy requires to put #[savvy] macro also on struct.

  #[savvy]   // NEW!
  struct Person {
      pub name: String,
  }
  #[savvy]
  impl Person {
  

  This might be a bit inconvenient on the one hand, but, on the other hand, several good things are introduced by this change! See the New Features section.

New features

• Now #[savvy] macro supports enum to express the possible options for a parameter. This is useful when you want to let users specify some option without fear of typo. See the guide for more details.

  Example:

  /// @export
  #[savvy]
  enum LineType {
      Solid,
      Dashed,
      Dotted,
  }
  /// @​export
  #[savvy]
  fn plot_line(x: IntegerSexp, y: IntegerSexp, line_type: &LineType) -> savvy::Result<()> {
  match line_type {
  LineType::Solid => {
  ...
  },
  LineType::Dashed => {
  ...
  },
  LineType::Dotted => {
  ...
