chore: bump savvy from 0.6.8 to 0.8.0 in /src/rust

[dependabot]

Bumps savvy from 0.6.8 to 0.8.0.

Changelog

Sourced from savvy's changelog.

[v0.8.0] (2024-10-31)

New feature

Like anyhow, now you can use ? to propagate any error that implements the std::error::Error trait.

#[savvy]
fn no_such_file() -> savvy::Result<()> {
    // previously, you had to write .map_err(|e| e.to_string().into())
    let _ = std::fs::read_to_string("no_such_file")?;
    Ok(())
}

If you want to implement your own error type and the conversion to savvy::Error, please specify use-custom-error feature to opt-out the auto-conversion to avoid conflict with impl From<dyn std::error::Error> for savvy::Error

savvy = { version = "...", features = ["use-custom-error"] }

Breaking change

By introducing the anyhow-like conversion, savvy loses the error conversion from a string (e.g. Err("foo".into())). Instead, please use savvy_err!() macro, which is a shorthand of Error::new(format!(...)).

#[savvy]
fn raise_error() -> savvy::Result<savvy::Sexp> {
    Err(savvy_err!("This is my custom error"))
}

Minor improvements

• NumericScalar::as_usize() and NumericSexp::iter_usize() now rejects numbers larger than 2^32 on 32-bit targets (i.e. webR). Thanks @​eitsupi!

[v0.7.2] (2024-10-27)

Minor improvements

• savvy now generates a reduced number of R functions.
