复合类型可以将多个值组合成一个类型。Rust 有两种基本的复合类型:元组(tuple)和数组(array)。 元组类型 元组是将多种类型的多个值组合到一个复合类型中的一种基本方式。元组的长度是固定的:声明后,它们就无法增长或缩小。 我们通过在小括号内写入以逗号分隔的值列表来创建一个元组。元组中的每个位置都有一个类型...
take all elements lower than n, a number passed as parameter by the user - as a reminder, if we explicit the final of the iterator, the compiler could decide to compute the final number at compile time, and store it in the executable -, and store the result in another array, loop al...
这里的Array类型就是上面的SomeType的一个例子。至于Array<Dog>到底是不是Array<Animal>的子类型呢,这个只和Array自己的性质有关 ,这个性质就是Variance。 但是Rust中让初学者很迷惑的一点是,Rust的类型不像Java/C++ 一样可以继承父类型,又哪里来的子类型呢?实际上,Rust有两种类型参数,一种是lifetime parameter,...
