v0.6.2 (2024-05-04)

Release Notes

New features

• New macro #[savvy_init] makes the function executed when the DLL is loaded
  by R. This is useful for initializaing resources. See the guide for more details.

  Example:

  use std::sync::OnceLock;
  
  static GLOBAL_FOO: OnceLock<Foo> = OnceLock::new();
  
  #[savvy_init]
  fn init_global_foo(dll_info: *mut DllInfo) -> savvy::Result<()> {
      GLOBAL_FOO.get_or_init(|| Foo::new());
  
      Ok(())
  }

• Savvy now experimentally supports ALTREP. See the guide for more details.

  Example:

  struct MyAltInt(Vec<i32>);
  
  impl MyAltInt {
      fn new(x: Vec<i32>) -> Self {
          Self(x)
      }
  }
  
  impl savvy::IntoExtPtrSexp for MyAltInt {}
  
  impl AltInteger for MyAltInt {
      const CLASS_NAME: &'static str = "MyAltInt";
      const PACKAGE_NAME: &'static str = "TestPackage";
  
      fn length(&mut self) -> usize {
          self.0.len()
      }
  
      fn elt(&mut self, i: usize) -> i32 {
          self.0[i]
      }
  }
