v0.4.1 (2024-03-30)

Release Notes

Breaking changes

• Sexp loses is_environment() method becuase this isn't useful, considering
  savvy doesn't support environment.

New features

• get_dim() and set_dim() are now available also on Sexp.

• Now savvy allows to consume the value behind an external pointer. i.e., T
  instead of &T or &mut T as the argument. After getting consumed, the
  pointer is null, so any function call on the already-consumed R object results
  in an error. See the guide for more details.

  Example:

  struct Value {};
  struct Wrapper { inner: Value }
  
  #[savvy]
  impl Value {
    fn new() -> Self {
      Self {}
    }
  }
  
  #[savvy]
  impl Wrapper {
    fn new(value: Value) -> Self {
      Self { inner: value }
    }
  }

  v <- Value$new()
  w <- Wrapper$new(v)  # value is consumed here.
  
  w <- Wrapper$new(v)
  #> Error: This external pointer is already consumed or deleted

• Sexp now has assert_integer() etc to verify the type of the underlying
  SEXP is as expected.
