1.First you create a separate struct that implements IJob, like this.

首先，您创建一个实现 IJob 单独结，如下所示。机翻

2.This needs to be a struct, not a class.

这需要是一个结，而不是一个类。机翻

3.The 680 bytes is important, because this struct here is exactly 680 bytes.

680 字节很重要，因为这里这个结正好是 680 字节。

4.Let's take a look at this struct that's called a " node" .

让看看这个称为“节点”结。机翻

5.We'll use this to initialize our struct and then give it the data it needs to do its work.

将使用它初始化结，然后为其提供完成工作所需据。机翻

6.Each struct implements the logic in the execute method, as we've already mentioned.

正如已经提到，每个结体都实现了执行方法中逻辑。机翻

7.Let's imagine we have three node structs saved in memory, at locations 1000, 1002 and 1008.

假设在内存中保存了三个节点结，位置分别为 1000、1002 和 1008。机翻

8.But, the struct data structure can be used for building more complicated data structures that avoid these restrictions.

但是，struct 据结可用于建更复据结，从而避免这些限制。机翻

9.It's basically just a C struct, a binary blob that is being thrown over a bulk endpoint to the device.

它基本上只是一个 C 结，一个二进制 blob，通过批量端点被抛到设备上。

10.In Swift, we use both value and reference types, and while NSCoding supports classes, it doesn't work at all with structs or enums.

在 Swift 里，会用到值类型和引用类型虽然 NSCoding 支持 类（class）但它对结（struct） 或者 枚举型（enum） 就无能为力了。

11.We can even make arrays of structs that we define, which are automatically bundled together in memory.

甚至可以创建定义结组，它会自动捆绑在内存中。机翻

12.Using this struct, we can create a linked list, which is a flexible data structure that can store many nodes.

使用这个结，可以创建一个链表，它是一种灵活据结，可以存储很多节点。机翻

13.This array of structs, like any other array, gets created at a fixed size that can't be enlarged to add more items.

与任何其他组一样，此结组以固定大小创建，无法扩大以添加更多项。机翻

14.You'll see shortly that a translation is just a struct.

您很快就会发现翻译只是一个结体。机翻

15.If it received more than 680 bytes at this point, we receive the header already, that big struct, and parts of the payload already.

如果此时它收到超过 680 个字节，已经收到了标头、那个大结和部分有效负载。

16.And this struct contains all the important things that the RCM code needs to know to verify that message, the signature of that message, and what it's supposed to do.

此结包含 RCM 代码验证该消息、该消息签名以及它应该执行操作所需知道所有重要内容。

17.If we access, for example, J index of 0, we get back the whole struct stored there, and we can pull the specific account number and balance data we want.

例如，如果访问 0 J 索引，会取回存储在那里整个结，并且可以提取想要特定帐号和余额据。机翻

18.So, a word like 'deconstruct' for example, the original word is 'construct' and that has a stress on the second syllable, 'construct' therefore, we keep that 'struct' stressed and we get 'deconstruct', so, 'construct', 'deconstruct'.

例如，像“deconstruct”这个单词，原始单词是“construct”，它重读在第二个音节，“construct”，所以，在“deconstruct”中重读还是在“struct”这里，所以，“construct”，“deconstruct”。
