Point to let when modifying field of immutable variable Point at the immutable local variable when trying to modify one of its fields. Given a file: ```rust struct Foo { pub v: Vec<String> } fn main() { let f = Foo { v: Vec::new() }; f.v.push("cat".to_string()); } ``` present the following output: ``` error: cannot borrow immutable field `f.v` as mutable --> file.rs:7:13 \| 6 \| let f = Foo { v: Vec::new() }; \| - this should be `mut` 7 \| f.v.push("cat".to_string()); \| ^^^ error: aborting due to previous error ``` 2017-03-11 11:11:50 -08:00			`20 \| let z = Z { x: X::Y };`
Change label to "consider changing this to `mut f`" Change the wording of mutable borrow on immutable binding from "this should be `mut`" to "consider changing this to `mut f`". 2017-03-12 13:49:28 -07:00			\| - consider changing this to `mut z`

borrowck: consolidate `mut` suggestions This converts all of borrowck's `mut` suggestions to a new `mc::ImmutabilityBlame` API instead of the current mix of various hacks. Fixes #35937. Fixes #40823. 2017-03-26 19:35:46 +03:00			error: cannot borrow immutable field `z.x` as mutable
