假设我有板条箱 A、B,我想将helper()板条箱 A 中的测试辅助函数共享给板条箱 B,所以我使用一个功能test-utils:
#[cfg(feature="test-utils")]\npub fn helper(){\n\n}\nRun Code Online (Sandbox Code Playgroud)\n所以问题是由于辅助函数包含对 A 中敏感数据的修改,我不希望在生产中编译该函数,例如cargo build --all-features.
有没有办法仅在测试中启用此功能,并在生产\xef\xbc\x9f 中禁用它

这是Cargo 所要求的功能,并且只能使用版本 2 解析器才能实现。如果板条箱 A 具有您提到的功能,那么板条箱 BCargo.toml可能包含
[package]
name = "B"
resolver = "2"
[features]
test-utils = []
[dependencies]
A = "*"
[dev-dependencies]
A = { version = "*", features = ["test-utils"] }
B = { path = ".", features = ["test-utils"] }

这将确保两个包仅在测试时才使用该test-utils功能构建。我用来跑步
[package]
name = "B"
resolver = "2"
[features]
test-utils = []
[dependencies]
A = "*"
[dev-dependencies]
A = { version = "*", features = ["test-utils"] }
B = { path = ".", features = ["test-utils"] }

并确保我确实得到了我在这两种情况下所要求的功能。
