Multiple mutable methods

help

Followup question... the following fails with

cannot borrow `*self` as mutable because it is also borrowed as immutable

struct Foo<'a> (&'a str);

impl<'a> Foo<'a> {
    fn init(self: &'a mut Self) {
        let value = self.get_value();
        self.do_something(value);
    }
    
    fn get_value(self: &'a Self) -> &'a str {
        self.0
    }
    
    fn do_something(self:&'a mut Self, _: &'a str) {
        
    }
}


fn main() {
    let mut foo = Foo ("hello world!");
    
    foo.init();
}

And if I change get_value to accept self: &'a mut Self then I get:

error[E0499]: cannot borrow `*self` as mutable more than once at a time

Ideas? Gotta run - but will be back later and excited to see some thoughts on this :slight_smile:
