Functions

func JsonValidator

func JsonValidator(v []byte) error

JsonValidator returns nil if input is valid json and ErrMalformedData otherwise.

Types

type Data

type Data []byte

Data define a slice of byte encoded.

type FasthttpArgsKeysValuesCollector

type FasthttpArgsKeysValuesCollector struct {
	Args           *fasthttp.Args
	Prefix         string
	ValueValidator func([]byte) error
}

FasthttpArgsKeysValuesCollector implements KvCollector. FasthttpArgsKeysValuesCollector collects values whose key have given prefix as raw string.

func (FasthttpArgsKeysValuesCollector) CollectKeysValues

func (fakvc FasthttpArgsKeysValuesCollector) CollectKeysValues() (keys, values []string, err error)

CollectKeysValues implements keysValuesCollector.

type FasthttpArgsKvView
