Nginx的内存管理都是围绕内存池来实现的,包括array数组类型也是基于Nginx的pool来实现数据结构。 Nginx的Array结构设计得非常小巧,主要用于存储小块内存。Nginx的数组每个元素的大小是固定的。 一、数据结构定义 ngx_array_t 数组的基础数据结构 /* 数组Array数据结构 */ typedef struct { void *elts; /* 指向数组...

@frozen struct Array<Element> Overview Arrays are one of the most commonly used data types in an app. You use arrays to organize your app’s data. Specifically, you use the Array type to hold elements of a single type, the array’s Element type. An array can store any kind of element...
