SErr package
The Structured Error package (serr) wraps errors for use with a structured logger like github.com/rohanthewiz/rlog.
This allows errors to be conveniently decorated with attributes and bubbled up from deep within a library without concern for actual logging within the library
Usage
(See the included tests for more examples)
package main
import (
"github.com/rohanthewiz/rlog
"github.com/rohanthewiz/serr
)
func ExerciseLogging() {
// Given an error
err := errors.New("Some error has occurred")
// We can wrap the error with a message
err2 := serr.Wrap(err, "Error occurred trying to do things")
// A structured error aware logger can output all attributes
rlog.LogErr(err2, "An Error occurred")
// => ERROR[0000] "An Error occurred msg="Error occurred trying to do things" error="Some error has occurred"
// We can wrap an error with some attributes
err3 := serr.Wrap(err, "cat", "aight", "dogs", "I dunno")
rlog.LogErr(err3, "Animals are cool")
// => ERRO[0000] Animals are cool cat=aight dogs="I dunno" error="Some error has occurred"
}
