Partition lifetimes of associated functions #1652

dtolnay · 2025-09-24T19:35:14Z

For this API:

unsafe extern "C++" {
    type Thing<'a>;
    fn f<'b, 'c>(self: &Thing<'b>, i: &'c CxxString);
}

Before:

impl<'b, 'c> Thing<'b> {
    pub fn f(&self, i: &'c CxxString) {...}
}

After:

impl<'b> Thing<'b> {
    pub fn f<'c>(&self, i: &'c CxxString) {...}
}

This is a prerequisite for #876.
