error[E0599]: no method named `f` found for unit type `()` in the current scope
--> $DIR/trait_items.rs:17:24
|
LL | fn f(&self) {}
| - the method is available for `()` here
...
LL | fn f() { ::baz::m!(); }
| ----------- in this macro invocation
...
LL | pub macro m() { ().f() }
| ^ method not found in `()`
|
= help: items from traits can only be used if the trait is in scope
= note: this error originates in the macro `::baz::m` (in Nightly builds, run with -Z macro-backtrace for more info)
help: the following trait is implemented but not in scope; perhaps add a `use` for it:
|
LL + use foo::T;
|
error: aborting due to previous error
For more information about this error, try `rustc --explain E0599`.
