Types

type HandlerFunc

type HandlerFunc func(ctx context.Context, payload []byte) ([]byte, error)

The HandlerFunc type is an adapter to allow the use of ordinary functions as Lambda Handlers. If f is a function with the appropriate signature, HandlerFunc(f) is a Handler that calls f.

func GenericHandler

func GenericHandler[I any, O any](handler func(context.Context, I) (O, error)) HandlerFunc

GenericHandler converts a typed lambda handler into a Handler func

func (HandlerFunc) Invoke

func (f HandlerFunc) Invoke(ctx context.Context, payload []byte) ([]byte, error)

Invoke calls f(ctx, payload).
