("number is not equal to 0"); } } Rust 执行上面示例代码,得到以下结果 - number is less than 0 Shell 在此示例中,变量num的值等于-5且num小于0。因此,else if块执行。 嵌套if-else语句 当if-else语句出现在另一个if或else块的主体内时,它称为嵌套if-else。嵌套if-else的语法 - if ...

Pathogen transmission could decline, however, if host survival rates also decrease under hotter, drier temperatures35. These complex, host–pathogen interactions36 may lead to highly variable disease range shifts (Fig. 1c), resulting in less predictable climate change impacts on disease risk17,32. ...

在Rust 中我们可以使用 if-else 结构实现类似于三元条件运算表达式 (A ? B : C) 的效果: fn main() {let a = 3;let number = if a > 0 { 1 } else { -1 };println!("number 为 {}", number);} 注意:两个函数体表达式的类型必须一样!且必须有一个 else 及其后的表达式块。
