fmt包下的Errorf函数可以将文本格式后作为error类型的错误信息,并返回一个error类型,因此其作用与errors.New函数类似 func getFile(name string)(*os.file,error){if name == ""{return nil,fmt.Errorf("file name could not be empty")}} fmt.Errorf函数还能封装其他error类型,再返回一个新的error类型,以此...
在C中,返回错误通过errno.h中的错误代码来表示,比如0代表No error,也就是没有错误;2代表No such file or directory,也就是找不到指定路径的文件或文件夹;5代表Input/Output error,表示输入或输出出现了错误... 而在我们最爱的Golang中,有这样一个饱受争议的error类型,它不是一个整数,而是一个接口。 复制 p...

例如,检查错误是否等于 io.EOF,您的代码必须导入 io 包。这个特定的例子听起来并不那么糟糕,因为它非常常见,但是想象一下,当项目中的许多包导出错误值时,存在耦合,项目中的其他包必须导入这些错误值才能检查特定的错误条件(in the form of an import loop)。

If there is no such API then could you please provide an API? We can call the API in the beginning of the program. Or can it be a build option? Best Regards Mariappan … Member ianlancetaylorcommentedJan 12, 2023 There is no API to avoid callingsigpanic, and we are not going to ...
