单二进制

这个 is available as of Rust 1.30 . 以下是我使用的完整文件集:

货物.toml

[workspace]
members = [
    "foo",
    "bar",
    "baz",
]

foo/货物.toml

[package]
name = "foo"
version = "0.1.0"
authors = ["An Devloper <an.devloper@example.com>"]

[dependencies]

foo/src/main.rs号

fn main() {
    println!("Hello, world!");
}

酒吧/货物.toml

[package]
name = "bar"
version = "0.1.0"
authors = ["An Devloper <an.devloper@example.com>"]

[dependencies]

钢筋/钢筋混凝土/lib.rs

#[cfg(test)]
mod tests {
    #[test]
    fn it_works() {
        assert_eq!(2 + 2, 4);
    }
}

baz/货物.toml

[package]
name = "baz"
version = "0.1.0"
authors = ["An Devloper <an.devloper@example.com>"]

[dependencies]

baz/src/lib.rs公司

#[cfg(测试)]
mod测试{
#[测试]
fn它有效(){
断言eq!(2+2,4);
}
}

多个二进制文件

从Rust1.37.0开始,您可以使用Cargo的“默认运行”功能来指定要使用哪一个。

foo/货物.toml

[package]
name = "foo"
version = "0.0.1"
authors = ["An Devloper <an.devloper@example.com>"]
default-run = "foo"
