Constants

const (
	RFC822TimeFormatName  = "rfc822"
	ISO8601TimeFormatName = "iso8601"
	UnixTimeFormatName    = "unixTimestamp"
)

Names of time formats supported by the SDK

const (
	// RFC 7231#section-7.1.1.1 timetamp format. e.g Tue, 29 Apr 2014 18:30:38 GMT
	RFC822TimeFormat = "Mon, 2 Jan 2006 15:04:05 GMT"

	// RFC3339 a subset of the ISO8601 timestamp format. e.g 2014-04-29T18:30:38Z
	ISO8601TimeFormat = "2006-01-02T15:04:05Z"
)

Time formats supported by the SDK

Variables

var RandReader = rand.Reader

RandReader is the random reader the protocol package will use to read random bytes from. This is exported for testing, and should not be used.

var UnmarshalDiscardBodyHandler = request.NamedHandler{Name: "awssdk.shared.UnmarshalDiscardBody", Fn: UnmarshalDiscardBody}

UnmarshalDiscardBodyHandler is a named request handler to empty and close a response's body

Functions

func CanSetIdempotencyToken

func CanSetIdempotencyToken(v reflect.Value, f reflect.StructField) bool

CanSetIdempotencyToken returns true if the struct field should be automatically populated with a Idempotency token.

Only *string and string type fields that are tagged with idempotencyToken which are not already set can be auto filled.

func DecodeJSONValue

func DecodeJSONValue(v string, escape EscapeMode) (aws.JSONValue, error)

DecodeJSONValue will attempt to decode the string input as a JSONValue. Optionally decoding base64 the value first before JSON unmarshaling.

Will panic if the escape mode is unknown.

func EncodeJSONValue

func EncodeJSONValue(v aws.JSONValue, escape EscapeMode) (string, error)

EncodeJSONValue marshals the value into a JSON string, and optionally base64 encodes the string before returning it.

Will panic if the escape mode is unknown.

func FormatTime

func FormatTime(name string, t time.Time) string

FormatTime returns a string value of the time.

func GetIdempotencyToken

func GetIdempotencyToken() string

GetIdempotencyToken returns a randomly generated idempotency token.

func IsKnownTimestampFormat

func IsKnownTimestampFormat(name string) bool

IsKnownTimestampFormat returns if the timestamp format name is know to the SDK's protocols.

func ParseTime

func ParseTime(formatName, value string) (time.Time, error)

ParseTime attempts to parse the time given the format. Returns the time if it was able to be parsed, and fails otherwise.

func SetIdempotencyToken

func SetIdempotencyToken(v reflect.Value)

SetIdempotencyToken will set the value provided with a Idempotency Token. Given that the value can be set. Will panic if value is not setable.

func UUIDVersion4

func UUIDVersion4(u []byte) string

UUIDVersion4 returns a Version 4 random UUID from the byte slice provided

func UnmarshalDiscardBody

func UnmarshalDiscardBody(r *request.Request)

UnmarshalDiscardBody is a request handler to empty a response's body and closing it.

func ValidHostLabel

func ValidHostLabel(label string) bool

ValidHostLabel returns if the label is a valid RFC 1123 Section 2.1 domain host label name.

Types

type EscapeMode

type EscapeMode uint

EscapeMode is the mode that should be use for escaping a value

const (
	NoEscape EscapeMode = iota
	Base64Escape
	QuotedEscape
)

The modes for escaping a value before it is marshaled, and unmarshaled.

type HandlerPayloadMarshal

type HandlerPayloadMarshal struct {
	Marshalers request.HandlerList
}

HandlerPayloadMarshal implements the PayloadMarshaler from a HandlerList. This provides support for marshaling a SDK shape into an io.Writer without needing a SDK request first.

func (HandlerPayloadMarshal) MarshalPayload

func (h HandlerPayloadMarshal) MarshalPayload(w io.Writer, v interface{}) error

MarshalPayload marshals the SDK shape into the io.Writer using the Marshalers HandlerList provided. Returns an error if unable if marshal fails.

type HandlerPayloadUnmarshal

type HandlerPayloadUnmarshal struct {
	Unmarshalers request.HandlerList
}

HandlerPayloadUnmarshal implements the PayloadUnmarshaler from a HandlerList. This provides the support for unmarshaling a payload reader to a shape without needing a SDK request first.

func (HandlerPayloadUnmarshal) UnmarshalPayload

func (h HandlerPayloadUnmarshal) UnmarshalPayload(r io.Reader, v interface{}) error

UnmarshalPayload unmarshals the io.Reader payload into the SDK shape using the Unmarshalers HandlerList provided. Returns an error if unable unmarshaling fails.

type PayloadMarshaler

type PayloadMarshaler interface {
	MarshalPayload(io.Writer, interface{}) error
}

PayloadMarshaler provides the interface for marshaling a SDK shape into and io.Writer.

type PayloadUnmarshaler

type PayloadUnmarshaler interface {
	UnmarshalPayload(io.Reader, interface{}) error
}

PayloadUnmarshaler provides the interface for unmarshaling a payload's reader into a SDK shape.
