img_err_cannot_find_fn_in_this_scope 在rust中也是一个{}之间为一个作用域。 是不是和别的语言差不多? 但其实rust中的函数还有一些自己的特点。 语句(statement)和表达式(expression)[2] 如果你学过babel[3],或者看过了解过ast(抽象语法树)。那么你应该看到过各种type: xxxExpression或者type: xxxStatem...

error[E0425]: cannot find value `x` inthisscope--> src/main.rs:174:24 | 174 | println!("x:{:?}",x);| 在Rust中也存在作用域概念,当资源离开作用域后,资源的内存就会被释放回收,当借用/引用离开作用域后也会被销毁,所以x在离开自已的作用域后,无法在作用域之外访问。
