如何从构建脚本(build.rs)访问当前货物档案(调试/发布等) [英] How to access current cargo profile (debug/release, …) from the build script (build.rs)
问题描述
在嵌入式项目中,我通常使用qemu运行调试模式,但需要为具体的微控制器构建发行版。
build.rs需要知道什么是实际模式(调试或释放)以生成正确的内存布局。
build.rs如何做出此决定?

它是用文档:
配置文件
-发布
用于发布版本,调试
用于其他版本。
<前置类= lang-rust prettyprint-override> fn main(){
let profile = std :: env :: var( PROFILE)。unwrap();
match profile.as_str(){
debug => (),
发行 => (),
_ => (),
}
}
In an embedded project, I usually run the debug mode with qemu, but need to build the release for a concrete microcontroller.
The build.rs would need to know what the actual mode is (debug or release) to generate the correct memory layout.
How can the build.rs make this decision?

It's written in the doc:
PROFILE
-"release"
for release builds,"debug"
for other builds.
fn main() {
let profile = std::env::var("PROFILE").unwrap();
match profile.as_str() {
"debug" => (),
"release" => (),
_ => (),
}
}
