E0049

Warning name: missing_definition

未使用的 pub 定义，因为它在 mbti 文件中不存在。

A .mbti file contains the public interface of a package. When a package implements a virtual package, it is checked against the interface of that virtual package, and this warning is emitted if extra public declarations are found.

错误示例

moon.pkg

options(
  "virtual": { "has-default": true },
)

pkg.mbti

package "moonbit-community/E0049"

top.mbt

///|
pub fn f() -> Unit {

}

建议

移除未出现在接口中的公共声明。
