error[E0382]: borrow of moved value: `message`
|
|
--> $DIR/liveness-use-after-send.rs:16:20
|
|
|
|
|
LL | fn test00_start(ch: Chan<Box<isize>>, message: Box<isize>, _count: Box<isize>) {
|
|
| ------- move occurs because `message` has type `Box<isize>`, which does not implement the `Copy` trait
|
|
LL | send(ch, message);
|
|
| ------- value moved here
|
|
LL | println!("{}", message);
|
|
| ^^^^^^^ value borrowed here after move
|
|
|
|
|
note: consider changing this parameter type in function `send` to borrow instead if owning the value isn't necessary
|
|
--> $DIR/liveness-use-after-send.rs:3:54
|
|
|
|
|
LL | fn send<T:Send + std::fmt::Debug>(ch: Chan<T>, data: T) {
|
|
| ---- in this function ^ this parameter takes ownership of the value
|
|
= note: this error originates in the macro `$crate::format_args_nl` which comes from the expansion of the macro `println` (in Nightly builds, run with -Z macro-backtrace for more info)
|
|
help: consider cloning the value if the performance cost is acceptable
|
|
|
|
|
LL | send(ch, message.clone());
