Types ¶
type DefaultCallbackHandler ¶
type DefaultCallbackHandler struct {
OnStart func(ctx context.Context, info *callbacks.RunInfo, input callbacks.CallbackInput) context.Context
OnStartWithStreamInput func(ctx context.Context, info *callbacks.RunInfo, input *schema.StreamReader[callbacks.CallbackInput]) context.Context
OnEnd func(ctx context.Context, info *callbacks.RunInfo, output callbacks.CallbackOutput) context.Context
OnEndWithStreamOutput func(ctx context.Context, info *callbacks.RunInfo, output *schema.StreamReader[callbacks.CallbackOutput]) context.Context
OnError func(ctx context.Context, info *callbacks.RunInfo, err error) context.Context
}
DefaultCallbackHandler is the default callback handler implementation, can be used for callback handler builder in template.HandlerHelper (for example, Graph, StateGraph, Chain, Lambda, etc.).
func (*DefaultCallbackHandler) Needed ¶
func (d *DefaultCallbackHandler) Needed(_ context.Context, _ *callbacks.RunInfo, timing callbacks.CallbackTiming) bool
Needed checks if the callback handler is needed for the given timing.
type HandlerHelper ¶
type HandlerHelper struct {
// contains filtered or unexported fields
}
HandlerHelper is a builder for creating a callbacks.Handler with specific handlers for different component types. create a handler with template.NewHandlerHelper(). eg.
helper := template.NewHandlerHelper().
ChatModel(&model.CallbackHandler{}).
Prompt(&prompt.CallbackHandler{}).
Handler()
then use the handler with runnable.Invoke(ctx, input, compose.WithCallbacks(handler))
func NewHandlerHelper ¶
func NewHandlerHelper() *HandlerHelper
NewHandlerHelper creates a new component template handler builder. This builder can be used to configure and build a component template handler, which can handle callback events for different components with its own struct definition, and fallbackTemplate can be used to handle scenarios where none of the cases are hit as a fallback.
func (*HandlerHelper) Chain ¶
func (c *HandlerHelper) Chain(handler *DefaultCallbackHandler) *HandlerHelper
Chain sets the chain handler for the handler helper, which will be called when the chain is executed.
func (*HandlerHelper) ChatModel ¶
func (c *HandlerHelper) ChatModel(handler *model.CallbackHandler) *HandlerHelper
ChatModel sets the chat model handler for the handler helper, which will be called when the chat model component is executed.
func (*HandlerHelper) Embedding ¶
func (c *HandlerHelper) Embedding(handler *embedding.CallbackHandler) *HandlerHelper
Embedding sets the embedding handler for the handler helper, which will be called when the embedding component is executed.
func (*HandlerHelper) Fallback ¶
func (c *HandlerHelper) Fallback(handler *DefaultCallbackHandler) *HandlerHelper
Fallback sets the fallback handler for the handler helper, which will be called when no other handlers are matched.
func (*HandlerHelper) Graph ¶
func (c *HandlerHelper) Graph(handler *DefaultCallbackHandler) *HandlerHelper
Graph sets the graph handler for the handler helper, which will be called when the graph is executed.
func (*HandlerHelper) Handler ¶
func (c *HandlerHelper) Handler() callbacks.Handler
Handler returns the callbacks.Handler created by HandlerHelper.
func (*HandlerHelper) Indexer ¶
func (c *HandlerHelper) Indexer(handler *indexer.CallbackHandler) *HandlerHelper
Indexer sets the indexer handler for the handler helper, which will be called when the indexer component is executed.
func (*HandlerHelper) Lambda ¶
func (c *HandlerHelper) Lambda(handler *DefaultCallbackHandler) *HandlerHelper
Lambda sets the lambda handler for the handler helper, which will be called when the lambda is executed.
func (*HandlerHelper) Loader ¶
func (c *HandlerHelper) Loader(handler *document.LoaderCallbackHandler) *HandlerHelper
Loader sets the loader handler for the handler helper, which will be called when the loader component is executed.
func (*HandlerHelper) Passthrough ¶
func (c *HandlerHelper) Passthrough(handler *DefaultCallbackHandler) *HandlerHelper
Passthrough sets the passthrough handler for the handler helper, which will be called when the passthrough is executed.
func (*HandlerHelper) Prompt ¶
func (c *HandlerHelper) Prompt(handler *prompt.CallbackHandler) *HandlerHelper
Prompt sets the prompt handler for the handler helper, which will be called when the prompt component is executed.
func (*HandlerHelper) Retriever ¶
func (c *HandlerHelper) Retriever(handler *retriever.CallbackHandler) *HandlerHelper
Retriever sets the retriever handler for the handler helper, which will be called when the retriever component is executed.
func (*HandlerHelper) StateGraph ¶
func (c *HandlerHelper) StateGraph(handler *DefaultCallbackHandler) *HandlerHelper
StateGraph sets the state graph handler for the handler helper, which will be called when the state graph is executed.
func (*HandlerHelper) Tool ¶
func (c *HandlerHelper) Tool(handler *tool.CallbackHandler) *HandlerHelper
Tool sets the tool handler for the handler helper, which will be called when the tool component is executed.
func (*HandlerHelper) ToolsNode ¶
func (c *HandlerHelper) ToolsNode(handler *DefaultCallbackHandler) *HandlerHelper
ToolsNode sets the tools node handler for the handler helper, which will be called when the tools node is executed.
func (*HandlerHelper) Transformer ¶
func (c *HandlerHelper) Transformer(handler *document.TransformerCallbackHandler) *HandlerHelper
Transformer sets the transformer handler for the handler helper, which will be called when the transformer component is executed.
