or_else 处理一个Result并返回一个Result,当前是某种错误时,通过传入的op方法,处理错误;如果是非错误类型,则不受影响。 pub fn or_else<F, O: FnOnce(E) -> Result<T, F>>(self, op: O) -> Result<T, F> { match self { Ok(t) => Ok(t), Err(e) => op(e), } } or_else 通常用于...
Rust支持所有整数类型的常规二进制运算,不过在做算术时不能混合不同的类型,而且与C不同的是,没有整型提升(integral promotion)。Rust中的溢出与C14不同:它是由实现定义的,并且必须使程序崩溃或回绕( wrap around)。Casting是通过as关键字完成的,其行为方式与C语言完全相同。(uint8_t) x被写成u8。整数类型之间从...
对同一个对象的不安全读写操作:比如边遍历一个vector边对这个vector做着一些插入删除操作。 C语言的思想是:尽量不对程序员做限制,尽量接近机器底层,类型安全、可变性、共享性都由程序员自由掌控,语言本身不提供太多的限制和规定。安全与否,也完全取决于程序员。所以要写好C代码肯定不会比写好Java简单的。 2.那么...
