-# Generics
+# 泛型
 
-Generics is the topic of generalizing types and functionalities to broader cases.
-This is extremely useful for reducing code duplication in many ways, but can call for rather involving syntax.
-Namely, being generic requires taking great care to specify over which types a generic type is actually considered valid.
-The simplest and most common use of generics is for type parameters.
+泛型的主旨是把类型和函数泛化到多种情况。
+这在很多方面有助于减少重复代码，但也可能需要为此使用相当多的语法。
+也就是说，使用泛型的话则需要小心谨慎地标明泛型适用于哪些类型。

 # Option
 
-Type Option represents an optional value: every Option is either Some and contains a value, or None, and does not. 
-Option types are very common in Rust code, as they have a number of uses:
-- Initial values
-- Return values for functions that are not defined over their entire input range (partial functions)
-- Return value for otherwise reporting simple errors, where None is returned on error
-- Optional struct fields
-- Struct fields that can be loaned or "taken"
-- Optional function arguments
-- Nullable pointers
-- Swapping things out of difficult situations
+Option 类型代表可选的值：每个 Option 要么是 Some ，包含一个值；要么是 None ，表示空值。
+Option 在 Rust 代码中十分常见，因为它有许多用途：
+- 初始值
+- 输入值不符合定义的情况下作为函数的返回值（部分函数）。
+- 返回 None 作为简单错误的返回值
+- 可选的结构字段
+- 可以借用或 "取走" 的结构字段（的值）
+- 可选的函数参数
+- 空指针
+- 在某些情况下交换值*
 
-## Further Information
+译注：“在某些情况下交换值”可以假设有个可变数组，现在要通过两个可变引用来交换其中两个元素的值。但 Rust 显然不允许有两个对数组的可变引用，这时候可以用 Option 包装下元素值，比如：
+
+``` rust
+fn main() {
+    let mut array = vec![Some(1), Some(2)];
+    let a = array.get_mut(0).unwrap().take().unwrap();
+    let b = array.get_mut(1).unwrap().replace(a);
+    *array.get_mut(0).unwrap() = b;
+    println!("{:?}", array);// [Some(2), Some(1)]
+}
+```
+
+嘿嘿，有点强行了。
