error[E0596]: cannot borrow `**layer` as mutable, as it is behind a `&` reference
|
|
--> $DIR/issue-115259-suggest-iter-mut.rs:15:65
|
|
|
|
|
LL | self.layers.iter().fold(0, |result, mut layer| result + layer.process())
|
|
| --------- ^^^^^ `layer` is a `&` reference, so the data it refers to cannot be borrowed as mutable
|
|
| |
|
|
| consider changing this binding's type to be: `&mut Box<dyn Layer>`
|
|
|
|
|
help: you may want to use `iter_mut` here
|
|
|
|
|
LL | self.layers.iter_mut().fold(0, |result, mut layer| result + layer.process())
