It is defined as follows:The error interface has only one method, namely the Error() method, which returns a string describing the error. This means that any type implementing the Error() method can be used as an error type.Typically, functions in Go programs return a value of the error type when encountering an error, allowing the caller to handle or log error information.How to construct an error?The designers of the Go language have provided two convenient methods for Go developers to construct error values: errors.New and fmt.Errorf.Using these two methods, we can easily construct an error value that satisfies the error interface, just like in the following code:These two methods actually return instances of the same unexplored type that implements the error interface.This unexported type is errors.errorString, and its definition is as follows:In most cases, error values constructed using these two methods will meet our needs.However, it’s important to note that while these methods are convenient for creating error values, the error context they provide to error handlers is limited to the…----ITNEXTI'm an independent entrepreneur, a developer and a father, enjoys speaking, writing, and sharing.DweninITNEXT--Jacob FerusinITNEXT--8Mahdi MallakiinITNEXT--1DweninITNEXT--Metakratos StudioinMetakratos Studio--Mehul Gohil--H.
