| error[E0507]: cannot move out of a shared reference |
| --> $DIR/suggest-clone-when-some-obligation-is-unmet.rs:20:28 |
| | |
| LL | let mut copy: Vec<U> = map.clone().into_values().collect(); |
| | ^^^^^^^^^^^ ------------- value moved due to this method call |
| | | |
| | move occurs because value has type `HashMap<T, U, Hash128_1>`, which does not implement the `Copy` trait |
| | |
| note: `HashMap::<K, V, S>::into_values` takes ownership of the receiver `self`, which moves value |
| --> $SRC_DIR/std/src/collections/hash/map.rs:LL:COL |
| note: if `Hash128_1` implemented `Clone`, you could clone the value |
| --> $DIR/suggest-clone-when-some-obligation-is-unmet.rs:8:1 |
| | |
| LL | pub struct Hash128_1; |
| | ^^^^^^^^^^^^^^^^^^^^ consider implementing `Clone` for this type |
| ... |
| LL | let mut copy: Vec<U> = map.clone().into_values().collect(); |
| | ----------- you could clone this value |
| help: you could `clone` the value and consume it, if the `Hash128_1: Clone` trait bound could be satisfied |
