Jorge Aparicio	759ac160db	remove the borrow_mut method from resources ... it can be used to break references rules within nested locks ``` rust static R1: Resource<bool, C1> = unsafe { Resource::new(false) }; static R2: Resource<bool, C2> = unsafe { Resource::new(false) }; static R3: Resource<bool, C3> = unsafe { Resource::new(false) }; // Priority = 1 extern "C" fn j1(task: interrupt::Exti0Irq) { R1.lock(&task, |r1, c1| { R2.lock(&task, |r2, c2| { R3.lock(&task, |r3, mut c3| { // BAD &- and &mut - that point to the same data let r1_ref: &bool = R1.borrow(&c2); let r1_ref_mut: &mut bool = R1.borrow_mut(&mut c3); }); }); }); } ```	2017-04-07 16:38:39 -05:00
