Types

type APIError 

type APIError struct {
	Code    APIErrorCode  `json:"code"`
	Message string        `json:"message"`

}

APIError represents the error from the CharmHub API.

func (APIError) Error

type APIErrorCode 

type APIErrorCode string

APIErrorCode classifies the error code we get back from the API. This isn't tautological list of codes.
