可以使用Cargo在发布模式下构建测试吗？

Question

I'm using cargo build --release to build my project in release configuration and cargo test to build and run my tests.

However, I'd like to also build my tests in release mode; can this be done using cargo?

Answer 1

cargo test --release exists, but it is slightly different than just enabling optimizations. For example, debug assertions become disabled.

You can also set opt-level in the [profile.test] section of your Cargo.toml, as Viktor Dahl suggests .
