Overview

Package arg2 contains tchannel thrift Arg2 interfaces for external use.

These interfaces are currently unstable, and aren't covered by the API backwards-compatibility guarantee.

Types

type KeyValIterator

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

KeyValIterator is a iterator for reading tchannel-thrift Arg2 Scheme, which has key/value pairs (k~2 v~2). NOTE: to be optimized for performance, we try to limit the allocation done in the process of iteration.

func NewKeyValIterator

func NewKeyValIterator(arg2Payload []byte) (KeyValIterator, error)

NewKeyValIterator inits a KeyValIterator with the buffer pointing at start of Arg2. Return io.EOF if no iterator is available. NOTE: tchannel-thrift Arg Scheme starts with number of key/value pair.

func (KeyValIterator) Key

func (i KeyValIterator) Key() []byte

Key Returns the key.

func (KeyValIterator) Next

func (i KeyValIterator) Next() (KeyValIterator, error)

Next returns next iterator. Return io.EOF if no more key/value pair is available.

func (KeyValIterator) Value

func (i KeyValIterator) Value() []byte

Value returns value.
