包路径：io.vavr.control.Option
类名称：Option
方法名：some

Option.some介绍

[英]Creates a new Some of a given value.

The only difference to Option#of(Object) is, when called with argument null.

Option.of(null);   // = None 
Option.some(null); // = Some(null)

[中]在给定的值中创建一个新的值。
与（Object）选项#的唯一区别是，当使用参数null调用时。

Option.of(null);   // = None 
Option.some(null); // = Some(null)
