v0.8.13 (2025-07-28)

Release Notes

New features

• Sexp now has .is_scalar_na(), which returns true if the SEXP is a length-1 of
  vector containing NA. This is useful when you want to let your function accept
  NA in addition to a typed vector (#391).

  #[savvy]
  fn some_func_handling_double(x: savvy::Sexp) -> savvy::Result<savvy::Sexp> {
      if x.is_scalar_na() {
          // treat NA
      }
  
      let x_real: RealSexp = x.try_into()?;
  
      ...

Release Notes

New features

• AltInteger and AltReal trait now provide sum(), min() and max() (#380).

Minor improvements

  compile error message (#382).
• The iterators returned by .iter() etc. are now properly annotated with
  lifetimes. This should not break any existing code, but please report if
  you find any issues.

Bug fixes

• Sexp::is_numeric() now returns false for a logical vector, e.g. NA (#387).
