error[E0659]: `empty_helper` is ambiguous (derive helper attribute vs any other name)
--> $DIR/helper-attr-blocked-by-import-ambig.rs:7:3
|
LL | #[empty_helper]
| ^^^^^^^^^^^^ ambiguous name
|
note: `empty_helper` could refer to the derive helper attribute defined here
--> $DIR/helper-attr-blocked-by-import-ambig.rs:10:10
|
LL | #[derive(Empty)]
| ^^^^^
note: `empty_helper` could also refer to the attribute macro imported here
--> $DIR/helper-attr-blocked-by-import-ambig.rs:5:5
|
LL | use test_macros::empty_attr as empty_helper;
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
= help: use `crate::empty_helper` to refer to this attribute macro unambiguously
warning: derive helper attribute is used before it is introduced
--> $DIR/helper-attr-blocked-by-import-ambig.rs:7:3
|
LL | #[empty_helper]
| ^^^^^^^^^^^^
...
LL | #[derive(Empty)]
| ----- the attribute is introduced here
