英文:
Rust, How to configure a workspace of libraries?
问题
I have a workspace lets call my_workspace. my_workspace has a series of small libraries related but each one with their own responsibility. Something like:
[workspace]
members = [
"my_lib_1",
"my_lib_2",
"my_lib_3",
...
]
And my_workspace are structured like this:
|my_lib_1/
|my_lib_2/
|my_lib_2/
|Cargo.toml
...
This workspace doesn't export any binaries only libraries.
The thing how I can configure my Cargo.toml to treat each members as a feature? to use like this:
# package that use the lib
[dependencies]
my_workspace = { ... , features = ["my_lib_1"] }
// inside of the package that use `my_workspace`
use my_workspace::my_lib_1;
fn do_something() {
my_lib_1::whatever_that_exposes_this_lib();
}
I'm sorry if this is a noob question, but I can't find any information in the cargo documentation that would shed light on how to accomplish this.

以下是翻译好的部分：
似乎 Rust 不允许我将工作区设置为 'main' 项目，因此我通过添加一个新的 crate 来解决，该 crate 导入了所有工作区成员，并在 Cargo.toml 中的 features 键以及每个成员的 lib.rs 中的 #[cfg(feature)] 注解中重新导出它们。

It seems like rust doesn't let me have a workspace as 'main' project, so instead I solved by adding a new crate that import all workspace members and reexport them with the features key in the Cargo.toml and the #[cfg(feature)] annotation in the lib.rs for each member.
