在fn前面加async error: async functions cannot be used for tests error[E0277]: the `?` operator can only be used in a function that returns `Result` or `Option` (or another type that implements `FromResidual`) 调用一个类的方法报错,this is an associated function, not a method 直接调用模...
即Rust 编译器不允许程序代码对不可变变量进行二次赋值。 可以通过let mut关键字声明可变变量。 fnmain(){letmutx=10;println!("The value is {}",x);x=20;println!("The value is {}",x);} $ cargo runFinisheddev[unoptimized+debuginfo]target(s)in0.29s Running `target/debug/variables`Thevalueis...

可以在 trait 定义的前面加上unsafe关键字来声明一个不安全 trait,同时该 trait 也只能在unsafe代码块中实现。 unsafetraitFoo{// 某些方法}unsafeimplFoofori32{// 对应的方法实现} 通过使用unsafe impl,我们向 Rust 保证我们会手动维护好那些编译器无法验证的不安全因素。 参考资料 The Rust Programming Language...
