版本没兼容导入的模块得使用extern修饰

[AliceLanniste]

我使用win10的操作系统，rust-version是1.3.1，cargo test时候，报出如下错误

error[E0658]: imports can only refer to extern crate names passed with `--extern` on stable channel (see issue #53130)
  --> src\lib.rs:50:9
   |
34 | mod compaction;
   | --------------- not an extern crate passed with `--extern`
...
50 | pub use compaction::ManualCompaction;
   |         ^^^^^^^^^^
   |
note: this import refers to the module defined here
  --> src\lib.rs:34:1
   |
34 | mod compaction;
   | ^^^^^^^^^^^^^^^

error[E0658]: imports can only refer to extern crate names passed with `--extern` on stable channel (see issue #53130)
  --> src\lib.rs:51:9
   |
35 | pub mod db;
   | ----------- not an extern crate passed with `--extern`
...
51 | pub use db::{WickDB, DB};
   |         ^^

  --> src\lib.rs:35:1
   |
35 | pub mod db;
   | ^^^^^^^^^^^

Thanks for the feedback! I’ll check this soon.

@AliceLanniste It seems this is related to the feature uniform path rust-lang/rust#56759. Could you please update rustc to 1.32 or newer and post the result of cargo test?

我明白了，顺便问句题外话，我的英语不是很好，你用全英文写文档以及回复我是怎么做到的，真诚的请教一下

再就是多参与一下其它开源项目，跟社区接触多了，常见的沟通语句见多了就会了

Close since we prefer using the latest stable rust :).
