| #### Note: this error code is no longer emitted by the compiler. | |
| This error indicates that the bindings in a match arm would require a value to | |
| be moved into more than one location, thus violating unique ownership. Code | |
| like the following is invalid as it requires the entire `Option<String>` to be | |
| moved into a variable called `op_string` while simultaneously requiring the | |
| inner `String` to be moved into a variable called `s`. | |
| Erroneous code example: | |
| ```compile_fail,E0382 | |
| #![feature(bindings_after_at)] | |
| let x = Some("s".to_string()); | |
| match x { | |
| op_string @ Some(s) => {}, // error: use of moved value | |
| None => {}, | |
| } | |
| ``` | |
