Library code shared among our repositories

vin utils

Use the VIN type for strings that are VIN's and it gets some basic decoding functionality (eg. year, or tesla model).

config loader

Convention over configuration library for typed configurations that can read from yaml file or env vars. Provides an opinionated way of dealing with configurations: for local development we want to use yaml config files, and on higher level environments we want settings to come from environment variables (we use kubernetes). Supported types are: string, int, int64, bool.

gRPC library

We should probably put these in the repositories of the services that own them, but we are putting this off for now. To make changes to the current suite for the device API, run

protoc --go_out=. --go_opt=paths=source_relative --go-grpc_out=. --go-grpc_opt=paths=source_relative api/devices/*.proto

Functions

func LoadConfig

func LoadConfig[S any](filePath string) (S, error)

LoadConfig fills in all the values in the Settings from local yml file (for dev) and env vars (for deployments)

Types

type CloudEventHeaders

type CloudEventHeaders struct {
	ID          string    `json:"id"`
	Source      string    `json:"source"`
	SpecVersion string    `json:"specversion"`
	Subject     string    `json:"subject"`
	Time        time.Time `json:"time"`
	Type        string    `json:"type"`
}

CloudEventHeaders contains the fields common to all CloudEvent messages.

type HTTPClientWrapper

type HTTPClientWrapper interface {
	ExecuteRequest(path, method string, body []byte) (*http.Response, error)
}

func NewHTTPClientWrapper

func NewHTTPClientWrapper(baseURL, torProxyURL string, timeoutSeconds time.Duration, headers map[string]string, addJSONHeaders bool) (HTTPClientWrapper, error)

type StringSet

type StringSet struct {
	// contains filtered or unexported fields
}

StringSet offers a nice api to deal with string lists

func NewStringSet

func NewStringSet() *StringSet

func (*StringSet) Add

func (s *StringSet) Add(st string)

func (*StringSet) Contains

func (s *StringSet) Contains(st string) bool

func (*StringSet) Len

func (s *StringSet) Len() int

func (*StringSet) Slice

func (s *StringSet) Slice() []string

type VIN

type VIN string

func (VIN) String

func (v VIN) String() string

func (VIN) TeslaModel

func (v VIN) TeslaModel() string

func (VIN) Year

func (v VIN) Year() int

Year will decode the year portion from the VIN from 1994 to 2023. returns 0 if out of range. VIN nomenclature only allows for 30 year timespans, then repeats, ie. 2023 = 1993
