Functions

func DefaultToHTTPError

func DefaultToHTTPError(_ error) int

DefaultToHTTPError is a ToHTTPError transalator that always returns an internal server error

func InitHTTPDefaultTransport

func InitHTTPDefaultTransport(cfg config.ServiceConfig)

InitHTTPDefaultTransport ensures the default HTTP transport is configured just once per execution

func NewServer

func NewServer(cfg config.ServiceConfig, handler http.Handler) *http.Server

NewServer returns a http.Server ready to serve the injected handler

func ParseTLSConfig

func ParseTLSConfig(cfg *config.TLS) *tls.Config

ParseTLSConfig creates a tls.Config from the TLS section of the service configuration

func RunServer

func RunServer(ctx context.Context, cfg config.ServiceConfig, handler http.Handler) error

RunServer runs a http.Server with the given handler and configuration. It configures the TLS layer if required by the received configuration.

Types

type ToHTTPError

type ToHTTPError func(error) int

ToHTTPError translates an error into a HTTP status code
