安装 Cargo 为打包目的构建的二进制文件的推荐方法是什么？

Question

How can I access the generated foo binary when I have this in my Cargo.toml?

[[bin]]
name = "foo"
path = "src/foo.rs"

Ideally I would like to have something which works like

make install DESTDIR=$(pwd)/i

I tried:

• cargo build --out-dir $(pwd)/i --> fails with "error: the --out-dir flag is unstable"

• cargo install --path . --root $(pwd)/i cargo install --path . --root $(pwd)/i --> comes near to the result, but it seems to be impossible to set flags like --release or its opposite variant (yes, I want the debug binary!)

• OUT_DIR=$(pwd)/i cargo build --> does not seem to have any effect as there is no directory generated

I could dig into the target directory, but there are a lot of unwanted files so globs will not work and I will have to know exactly the artifact name, including automatic suffices like .a , .so , .so.1.2.3 , etc.

How to access binaries built by cargo?

The cargo install --path . --root $(pwd)/i cargo install --path . --root $(pwd)/i is the correct way to specify the destination installation directory.

but it seems to be impossible to set flags like --release or its opposite variant (yes: I want the debug binary!)

It's possible with the --debug flag.

cargo install --debug --path . --root $(pwd)/i

See cargo install manual .
