crates/cairo-lang-syntax/src/node/mod.rs line 86 at r1 (raw file):

        TextSpan { start, end }
    }
    pub fn children<'db>(&self, db: &'db dyn SyntaxGroup) -> SyntaxNodeChildIterator<'db> {

I've tried removing this function in a single PR.
If you think this PR is too large I can split it.

Code quote:

 pub fn children<'db>(&self, db: &'db dyn SyntaxGroup) -> SyntaxNodeChildIterator<'db>
