The error report allows to collect errors and adding metadata and flags to them.

    flagSerious yeterr.ErrorFlag = "serious"
)

func example() {
    report := yeterr.NewSimpleReport()
    report.AddError(errors.New("not flagged"), nil)
    report.AddFlaggedError(errors.New("warning"), yeterr.Metadata{"time", time.Now().String()}, flagWarning)
    report.AddFlaggedError(errors.New("serious"), yeterr.Metadata{"time": time.Now().String()}, flagSerious)
    report.AddFlaggedFatalError(errors.New("really serious"), nil, flagSerious)

    seriousErrors := report.FilterErrorsByFlag(flagSerious) // 2 items
    fatalSeriousError := report.FatalError() // returns the "really serious" error
}
