Test case:
fn main() {}
struct A;
impl A {
fn b(&mut self) {
self.a()
}
}
trait Foo {}
trait Bar {
fn a(&self);
}
impl Foo for A {}
impl<T> Bar for T where T: Foo {
fn a(&self) {}
}rustc output:
a.rs:7:9: 7:17 error: the trait `Foo` is not implemented for the type `&mut A`
a.rs:7 self.a()
^~~~~~~~
error: aborting due to previous error
Expected behavior: &mut self is automatically converted to &self in the self.a() call.
The bug disappears if fn b is changed to take &self, if fn a is changed to take &mut self, or if the call is changed to (&*self).a().
