 # Traits
 
-A trait is a collection of methods.
+Trait 是一系列方法的集合。
 
-Data types can implement traits. To do so, the methods making up the trait are defined for the data type. For example, the `String` data type implements the `From<&str>` trait. This allows a user to write `String::from("hello")`.
+数据类型可以实现 trait。为此需要帮数据类型定义好构成 trait 的方法。 
+例如，`String` 类型实现了 `From<&str>` trait。它赋予我们能力写出 `String::from("hello")`。
 
-In this way, traits are somewhat similar to Java interfaces and C++ abstract classes.
+如此一来，trait 就有点类似于 Java 的接口和 C++ 的抽象类。
 
-Some additional common Rust traits include:
-- `Clone` (the `clone` method)
-- `Display` (which allows formatted display via `{}`)
-- `Debug` (which allows formatted display via `{:?}`)
+另外一些常见的 Rust trait 包括：
+- `Clone` （`clone` 方法）
+- `Display` (实现通过 `{}` 进行格式化显示)
+- `Debug` (实现通过 `{:?}` 进行格式化显示 )
 
-Because traits indicate shared behavior between data types, they are useful when writing generics.
+因为 trait 标明了数据类型之间的共有行为，所以它在编写泛型时非常有用。
