The idiomatic way of handling errors in Go is to compare the returned error tonil. A nil value indicates that no error has occurred and a non-nil value indicates the presence of an error.In our case, we check whether the error is notnilin line no. 10. If it is notnil, we simply...
需要自己用map实现,不像java,string interning(字符串驻留)是内置模式。 标准库: bytes参数是[]byte类型,还提供了Buffer类型用于字节slice的缓存,bytes.Buffer的WriteRune/WriteByte strings提供了Contains、Compare等方法 strconv提供了布尔型、整型数、浮点数和对应字符串的相互转换,还提供了双引号转义相关的转换。
这也许是Go语言团队引入泛型后的最大担忧：像C++那样被滥用而形成很多奇技淫巧。因此也给出了泛型使用...
In the uncommon case that you have a value struct that you don’t want compared, then adding a doNotCompare field will give you the freedom to change the struct later without having to worry about breaking comparisons. On the downside, the type won’t be usable as a map key....
The Zero function has been optimized to avoid allocations. Code which incorrectly compares the returned Value to another Value using == or DeepEqual may get different results than those obtained in previous Go versions. The documentation forreflect.Valuedescribes how to compare twoValues correctly. ...
