max:最大值,小于等于参数值,validate:"max=20"(小于等于20) min:最小值,大于等于参数值,validate:"min=2,max=20"(大于等于2小于等于20) ne:不等于,validate:"ne=2"(不等于2) oneof:只能是列举出的值其中一个,这些值必须是数值或字符串,以空格分隔,如果字符串中有空格,将字符串用单引号包围,validate:...
s := []int{1,2} s = append(s, 3,4,5) println(cap(s)) } // output: 6 为什么结果不是5,不是8,而是6呢?由于小菜刀在该文中关于扩容的描述不够准确,让读者产生了疑惑。因此本文想借此机会细致分析一下append函数及其背后的扩容机制。
