CircleCI Go Report Card codecov GoDoc
An error implementation with StatusCode and Stacktrace
It implements the Golang error interface
You can use Status Code to better identify the answer you need to report to the client.
Makes debugging easier by logging the functions the error passes through and by adding the ability to log context on each function pass of the error, so that you can create a path of the error through your application.
$ go get github.com/efimovalex/stackerrpackage main import ( "fmt" "net/http" "github.com/efimovalex/stackerr" ) func f1() *stackerr.Err { err := stackerr.NewWithStatusCode("message", http.StatusNotFound) return err.Stack() } func f2() *stackerr.Err { err := f1() return err.StackWithContext("context") } type t1 struct{} func (t *t1) f3() *stackerr.Err { err := f2() return err.Stack() } func main() { ts := t1{} err := ts.f3() fmt.Println(err.Sprint()) fmt.Println(err.Error()) fmt.Println(err.StatusCode) if err.IsNotFound() { fmt.Println("Resource is not found") } err.Log() }
