v0.6.3 (2024-05-05)

Release Notes

New features

• New types NumericSexp and NumericScalar are added to handle both integer
  and double. You can get a slice via as_slice_*() or an iterator via
  iter_*().

  #[savvy]
  fn times_two(x: NumericSexp) -> savvy::Result<Sexp> {
      let mut out = OwnedIntegerSexp::new(x.len())?;
  
      for (i, v) in x.iter_i32().enumerate() {
          let v = v?; // The item of iter_i32() is Result because the conversion can fail.
          if v.is_na() {
              out[i] = i32::na();
          } else {
              out[i] = v * 2;
          }
      }
  
      out.into()
  }

  You can also use .into_typed() to handle integer and double differently.

  #[savvy]
  fn times_two(x: NumericSexp) -> savvy::Result<savvy::Sexp> {
      match x.into_typed() {
          NumericTypedSexp::Integer(i) => times_two_int(i),
          NumericTypedSexp::Real(r) => times_two_real(r),
      }
  }

• Savvy now provides r_stdout() and r_stderr() to be used with interfaces
  that require std::io::Write. Also, you can use savvy::log::env_logger() to
  output logs to R's stderr. Here's an example usage:

  use savvy::savvy_init;
  use savvy_ffi::DllInfo;
  
  #[savvy_init]
  fn init_logger(dll_info: *mut DllInfo) -> savvy::Result<()> {
      savvy::log::env_logger().init();
      Ok(())
  }

Breaking changes

• AltList now loses names argument in into_altrep() for consistency.
  Please use set_names() on the resulted Sexp object.

  let mut out = v.into_altrep()?;
  out.set_names(["one", "two"])?;
  Ok(out)
