Simple error package

Simple abstraction for errors.

Use this package for create a new error. An error in Go is any implementing interface with an Error() string method. We overwrite the error object by our error struct:

type Error struct {
	Err   error
	Type  Type
	meta  map[string]interface{}
	stack []string
}

To be easier the error construction, the package provides a function named E, which is short and easy to type:

func E(args ...interface{}) *Error

E.g.:

• just error:

errors.E(err)

• error with message:

errors.E(err, "new message to append")

• error with type:

errors.E(err, errors.TypePlatformReques)

• error with type and message:

errors.E(err, errors.TypePlatformReques, "new message to append")

• error with type and meta:

errors.E(err, errors.TypePlatformRequest, errors.Params{
			"coin":   "Ethereum",
			"method": "CurrentBlockNumber",
		})

• error with meta:

errors.E(err, errors.Params{
			"coin":   "Ethereum",
			"method": "CurrentBlockNumber",
		})

• error with type and meta:

errors.E(err, errors.TypePlatformRequest, errors.Params{
			"coin":   "Ethereum",
			"method": "CurrentBlockNumber",
		})

• error with type, message and meta:

errors.E(err, errors.TypePlatformRequest, "new message to append", errors.Params{
			"coin":   "Ethereum",
			"method": "CurrentBlockNumber",
		})

• You can send the errors to sentry using .PushToSentry()

errors.E(err, errors.TypePlatformReques).PushToSentry()
