error[E0392]: type parameter `T` is never used
--> $DIR/inline-tainted-body.rs:7:21
|
LL | pub struct WeakOnce<T>();
| ^ unused type parameter
|
= help: consider removing `T`, referring to it in a field, or using a marker such as `PhantomData`
= help: if you intended `T` to be a const parameter, use `const T: /* Type */` instead
error: functions with the "rust-call" ABI must take a single non-self tuple argument
--> $DIR/inline-tainted-body.rs:11:35
|
LL | extern "rust-call" fn try_get(&self) -> Option<Arc<T>> {}
| ^^^^^
error[E0308]: mismatched types
--> $DIR/inline-tainted-body.rs:11:45
|
LL | extern "rust-call" fn try_get(&self) -> Option<Arc<T>> {}
| ------- ^^^^^^^^^^^^^^ expected `Option<Arc<T>>`, found `()`
| |
| implicitly returns `()` as its body has no tail or `return` expression
|
= note: expected enum `Option<Arc<T>>`
found unit type `()`
error: aborting due to 3 previous errors
Some errors have detailed explanations: E0308, E0392.
