The syntax for the if-else statement in Rust is provided below: ifboolean_expression { //dothis } else { //thendothis } Note: the else keyword comes immediately after closing the curly brace of the if block. Consider the sample code shown below: fnmain() { let weather = "sunny"; ...
To handle the basic flow of Rust code, two keywords are used: if and else. This helps you create two "execution paths" based on the state of the provided condition. The syntax of a simple if block with an alternative execution path is as follows: if condition { <statement(s)>; } el...
Rust if语句 if语句确定条件是否为真。如果条件为true,则执行if块,否则,控制会跳过if块。 表示if块的几种方式: if块 if-else块 if else-if阶梯块 嵌套if语句 if语句 if语句块的语法 - if condition { //block statements; } 在上面的语法中,如果条件为真,则执行块语句,否则跳过if块。
