Functions

func LoggingContractId

func LoggingContractId() string

LoggingContractId returns the capability contract id for this interface

func LoggingHandler

func LoggingHandler(actor_ Logging) actor.Handler

LoggingHandler is called by an actor during `main` to generate a dispatch handler The output of this call should be passed into `actor.RegisterHandlers`

Types

type LogEntry

type LogEntry struct {
	// severity level: debug,info,warn,error
	Level string
	// message to log
	Text string
}

func CDecodeLogEntry

func CDecodeLogEntry(d *cbor.Decoder) (LogEntry, error)

CDecodeLogEntry deserializes a LogEntry using cbor

func MDecodeLogEntry

func MDecodeLogEntry(d *msgpack.Decoder) (LogEntry, error)

MDecodeLogEntry deserializes a LogEntry using msgpack

func (*LogEntry) CEncode

func (o *LogEntry) CEncode(encoder cbor.Writer) error

CEncode serializes a LogEntry using cbor

func (*LogEntry) MEncode

func (o *LogEntry) MEncode(encoder msgpack.Writer) error

MEncode serializes a LogEntry using msgpack

type Logging

type Logging interface {
	//
	// WriteLog - log a text message
	//
	WriteLog(ctx *actor.Context, arg LogEntry) error
}

type LoggingReceiver

type LoggingReceiver struct{}

LoggingReceiver receives messages defined in the Logging service interface

func (*LoggingReceiver) Dispatch

func (r *LoggingReceiver) Dispatch(ctx *actor.Context, svc interface{}, message *actor.Message) (*actor.Message, error)

type LoggingSender

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

LoggingSender sends messages to a Logging service

func NewProviderLogging

func NewProviderLogging() *LoggingSender

NewProvider constructs a client for sending to a Logging provider implementing the 'wasmcloud:builtin:logging' capability contract, with the "default" link

func NewProviderLoggingLink

func NewProviderLoggingLink(linkName string) *LoggingSender

NewProviderLoggingLink constructs a client for sending to a Logging provider implementing the 'wasmcloud:builtin:logging' capability contract, with the specified link name

func (*LoggingSender) WriteLog

func (s *LoggingSender) WriteLog(ctx *actor.Context, arg LogEntry) error

WriteLog - log a text message
