问题描述
我有一些示例代码目前正在使用 getopts,它被指定为 getopts代码>Cargo.toml
I have some sample code that is currently making use of getopts which is specified as a dependency in Cargo.toml
[dependencies]
getopts = "0.2"
但是我似乎无法通过 Cargo 传递参数 (-t
, --test
)(例如 cargo run --test
)出于显而易见的原因.
However I can not seem to pass argument (-t
, --test
) through Cargo (e.g. cargo run --test
) for obvious reasons.
因为我已经指定了外部依赖,尝试运行 rustc src/main.rs --test
也不会工作:
Since I have specified that external dependency, trying to run rustc src/main.rs --test
won't work either:
src/main.rs:2:5: 2:21 error: unresolved import `getopts::Options`. There is no `Options` in `getopts`
src/main.rs:2 use getopts::Options;
^~~~~~~~~~~~~~~~
error: aborting due to previous error
是否有其他方法可以实现这一目标或目前有一些常见的替代方法?
Is there another way to achieve this or some common alternative for the time being?
推荐答案
您可以使用 --
将尾随参数传递给 cargo run
:
You can pass trailing arguments to cargo run
using --
:
cargo run -- --test
从 man
页面:
所有尾随参数都传递给要运行的二进制文件.如果你路过Cargo 和二进制文件的参数, --
之后的那些转到二进制文件,去 Cargo 之前的那些.
