rust calling mutable self function from mutable self function

Comment

Simplest answer for me was to declare the mutable borrows in the second function. If foo calls bar, do the mutable borrowing inside bar instead of passing bar a mutable reference, which doesn't work.

pub fn foo(&mut self, thingid: u32) {
    //stuff
    self.bar(&thingid);
}
pub fn bar(&mut self, thingid: u32) {
    self.things.get_mut(&thingid).unwrap();
    //stuff
}
