Function normalize_r_arg_ident 

Source 
pub fn normalize_r_arg_ident(rust_ident: &Ident) -> Ident
Expand description

Normalizes Rust argument identifiers for R.

  • Leading _ → stripped (Rust convention for unused params)
  • Leading __ → stripped
  • Otherwise → unchanged

§Examples

  • _x → x
  • _to → to
  • __field → field
  • value → value

Note: We strip underscores rather than prefixing “unused” because R callers (like vctrs) may use named arguments that must match the original name.
