「Rust 强制要求开发者处理所有可能的错误情况。如果一个函数返回Result类型,你必须显式处理Ok和Err,或者使用unwrap()、expect()等方法明确标明这里可能的错误不会被处理。当然,这将在运行时引发 panic,如果预期的错误发生的话。」 「Rust 编译器会在编译时捕获未处理的Result和Option类型,要求程序员处理,否则就编译...
由于testcrate依赖于标准库,所以它在我们的裸机目标上并不可用,虽然将testcrate移植到一个#[no_std]上下文环境中是可能的,但是这样做是高度不稳定的并且还会需要一些特殊的hacks,例如重定义panic宏。 自定义测试框架 幸运的是,Rust支持通过使用不稳定的 [自定义测试框架(custom_test_frameworks)] 功能来替换默认的测...
