Types

type AgentFinalStreamHandler 

type AgentFinalStreamHandler struct {
	SimpleHandler

	Keywords        []string
	LastTokens      string
	KeywordDetected bool
	PrintOutput     bool
	// contains filtered or unexported fields
}

func NewFinalStreamHandler 

func NewFinalStreamHandler(keywords ...string) *AgentFinalStreamHandler

NewFinalStreamHandler creates a new instance of the AgentFinalStreamHandler struct.

It accepts a variadic number of strings as keywords. If any keywords are provided, the DefaultKeywords variable is updated with the provided keywords.

DefaultKeywords is map of the agents final out prefix keywords.

The function returns a pointer to the created AgentFinalStreamHandler struct.

func (*AgentFinalStreamHandler) GetEgress 

func (handler *AgentFinalStreamHandler) GetEgress() chan []byte

GetEgress returns the egress channel of the AgentFinalStreamHandler.

It does not take any parameters. It returns a channel of type []byte.

func (*AgentFinalStreamHandler) HandleStreamingFunc 

func (handler *AgentFinalStreamHandler) HandleStreamingFunc(_ context.Context, chunk []byte)

HandleStreamingFunc implements the callback interface that handles the streaming of data in the AgentFinalStreamHandler. The handler reads the incoming data and checks for the agents final output keywords, ie, `Final Answer:`, `Final:`, `AI:`. Upon detection of the keyword, it starst to stream the agents final output to the egress channel.

It takes in the context and a chunk of bytes as parameters. There is no return type for this function.

func (*AgentFinalStreamHandler) ReadFromEgress 

func (handler *AgentFinalStreamHandler) ReadFromEgress(
	ctx context.Context,
	callback func(ctx context.Context, chunk []byte),
)

ReadFromEgress reads data from the egress channel and invokes the provided callback function with each chunk of data.

The callback function receives two parameters: - ctx: the context.Context object for the egress operation. - chunk: a byte slice representing a chunk of data from the egress channel.
