Rust error E0007: #### Note: this error code is no longer emitted by the compiler
What it means#### Note: this error code is no longer emitted by the compiler.
Retired: rustc no longer emits this error code. You may still see it in old answers, books and CI logs from older toolchains; the explanation below is kept for reference.
The compiler team's explanation
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:
#![feature(bindings_after_at)]
let x = Some("s".to_string());
match x {
op_string @ Some(s) => {}, // error: use of moved value
None => {},
}See also the error E0303.
