json 使用 gin 类似的可选组织方式:

  • go build . 默认使用 json-iterator/go
  • go build -tags=stdjson . 使用标准 JSON 库 encoding/json
  • go build -tags=gojson . 使用 goccy/go-json

指针是非复合类型, 赋值 nil 时, 将 8 字节置 0, 即没有指向任何值的指针 0x0
map, channel: var 时仅定义了指针, 需要 make 初始化内部结构后才能使用, make 后非 nil

var 若变量非指针, 如 struct, int, 非 nil slice: 

type slice struct, 占用 24 字节, 1 指针(array unsafe.Pointer) 2 个整型字段(len, cap int)
var 定义后即可使用, 置 0 并分配, 此时 array 指针为 0 即没有实际数据时为 nil

interface: 

type iface struct(interface 类型), type eface struct(空接口), 占用 16 字节
判断 data 指针为 0 即为 nil, 初始化后即非 0
