A sector is like a “pizza slice” of the circle. It consists of a region bounded by two radii and an arc lying between the radii. The area of a sector is a fraction of the area of the circle. This area is proportional to the central angle. In other words, the bigger the central...
在下面的示例模块树中,lib.rs是crate的根模块,shapes和math是它的子模块。circle和rectangle是shapes的子模块,algebra和geometry是math的子模块。shapes之所以是模块,是因为shapes文件夹下有一个mod.rs文件。math之所以是模块,是因为math同级目录下有一个同名的math.rs文件。在后面内容的介绍当中,我们也会用到这里的示...
