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

需要是构，而不是类。机翻

2.Groups of variables like these can be bundled together into a Struct.

像样的变量组可以捆绑在起成为构。机翻

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

来看看称为“节点”的构。机翻

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

首先，您创建实现 IJob 的单独构，如下所示。机翻

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

将使用它来初始化的构，然后为其提供完成工作所需的数据。机翻

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

680 字节很重要，因为里的构正好是 680 字节。

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

正如已经提到的，每构体都实现了执行方法中的逻辑。机翻

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

甚至可以创建定义的构数组，它会自动捆绑在内存中。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 C 构，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）但它对构（struct） 或者 枚举型（enum） 就无能为力了。

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

但是，struct 数据构可用于构建更复杂的数据构，从而避免些限制。机翻

12.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节点构，位置分别为 1000、1002 和 1008。机翻

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

使用构，可以创建链表，它是种灵活的数据构，可以存储很多节点。机翻

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

与任何其他数组样，此构数组以固定大小创建，无法扩大以添加更多项。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 字节，已经收到了标头、那大构和部分有效负载。

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

您很快就会发现翻译只是构体。机翻

17.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.

此构包含 RCM 代码验证该消息、该消息的签名以及它应该执行的操作所需知道的所有重要内容。

18.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 的 J 索引，会取回存储在那里的整构，并且可以提取想要的特定帐号和余额数据。机翻

19.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”单词，原始单词是“construct”，它的重读在第二音节，“construct”，所以，在“deconstruct”中的重读还是在“struct”里，所以，“construct”，“deconstruct”。
