for character in self.iterator.by_ref() { // If it encounters a closing `"`, break // out of the loop as the string has ended. if character == '"' { break; } // Continue pushing to the vector to build // the string. string_characters.push(character); } // Create a string ...
这种模式可以通过loop,if,else以及break关键字的组合使用来实现。 由于这种模式太过于常见,Rust提供了一个内置的语言结构:While循环。如下面的代码示例,程序会执行3次,每次减1,在循环结束之后打印出特定的消息并退出。 src/main.rs fn main(){ let mut number = 3; while number!=0{ println!("{}!",number...
Create string t from string s, keeping only digit characters 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.

Outside of a for loop, set_global is exactly the same as set. 过滤器(Filters) 可以使用过滤器修改变量 在变量名称后面添加一个|,再后面就可以跟上过滤器名称和参数(如果有)来使用过滤器了。 可以一次使用多个过滤器,前面过滤器的输出是后面过滤器的输入. You can modify variables using filters. Filters...
