RNIB Queries Request Overview

The purpose of this document is to describe the RNIB Queries the E2M supplies: Input and Output.

Error Handling

We defined few custom errors that implement error interface

type InternalError struct{
err error
}

func NewInternalError(error error) error {
return &InternalError{err:error}
}

func (e InternalError) Error() string {
return e.err.Error()
}

type ResourceNotFoundError struct{
	message string
}

func NewResourceNotFoundError(msg string) error {
	return &ResourceNotFoundError{message:msg}
}

func NewResourceNotFoundErrorf(fmtMsg string, a ...interface{}) error {
	return &ResourceNotFoundError{message:fmt.Sprintf(fmtMsg, a...)}
}

func (e ResourceNotFoundError) Error() string {
	return e.message
}

type ValidationError struct{
	message string
}

func NewValidationError(msg string) error {
	return &ValidationError{message:msg}
}

func NewValidationErrorf(fmtMsg string, a ...interface{}) error {
	return &ValidationError{message: fmt.Sprintf(fmtMsg, a...)}
}

func (e ValidationError) Error() string {
	return e.message
}
