This function has no return value . It returns a result just like other functions. We use T again as the return type. If the return value is 0, it has the sign of x.
You will see that the value of b really is None. But we can also use the returned function as a value :. Not the return value of say, but say itself! How is it possible to return a value from a function? Return_type is a number that determines the type of return value . Try is an expression, so it can return a result . Query: returns a value , but does not change the state of the system. Try is an expression, so it can return a result . Commands change the state of the system, but do not return a value . If there are two return values , the second value must implement error. In the UNIX system, the status return is the value returned by exit. Encapsulates a method that has 10 parameters and does not return a value . 但是在ECMAScript标准化之前,该方法无返回值 。 Prior to ECMAScript standardization, this method returns nothing. This operator specifies an expression to be evaluated without returning a value . These names should be used to document the meaning of the return values . DoInput和doPrint这两种函数都会返回值 ,而且返回的值都为操作。 Both the doInput and doPrint functions return values , and in both cases, the values are actions. If the lock is available this method returns immediately with the value true. Five函数的返回值是5,所以返回值 类型是i32。 The 5 in five is the function's return value,which is why the return type is i32. 而在这个例子中,substr的返回值 不变,但是它会改变原来字符串的内容! In this example, the return value of substr will still behave the same way, but substr will also change the content of the original string! 一旦命名了返回值 ,可以认为这些值在函数第一行就被声明为变量了。 If a return value is named, it can be considered as being declared as a variable in the first line of the function. 因为同步调用通常都有返回值 ,终究,返回值都是隐式“请求(ask)”的结果。 Synchronous calls often return values , and after all, a return value is the result of an implicit‘ask'. 调用一个有返回值的函数会生成一个返回值 ,我们通常将其赋值给某个变量或是作为表达式的一部分。 Calling the function generates a return value , which we usually assign to a variable or use as part of an expression. 这个公有方法没有返回值 ,但被修改成了返回用户类实例的方法。 There was no return value of the method as public, but it later has been changed to return the user class instance. 调用一个有返回值的函数会生成一个返回值 ,我们通常将其赋值给某个变量或是作为表达式的一部分。 Calling each of these functions generates a value , which we usually assign to a variable or use as part of an expression.
