Types

type Executor

type Executor interface {
	HandleMessage(context.Context, *Message, ReplyFunc)
	Stop()
}

func NewLuaExecutor

func NewLuaExecutor(c context.Context, store msgstore.ScriptStore, plugins []msgplugins.PreloadFunc, nc *nats.Conn) Executor

NewLuaExecutor creates a new ScriptExecutor using the provided ScriptStore

func NewWasmExecutor

func NewWasmExecutor(c context.Context, store msgstore.ScriptStore, plugins []msgplugins.PreloadFunc, nc *nats.Conn) Executor

type LuaExecutor

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

LuaExecutor defines the structure responsible for managing Lua script execution

func (*LuaExecutor) HandleMessage

func (le *LuaExecutor) HandleMessage(ctx context.Context, msg *Message, rf ReplyFunc)

HandleMessage receives a message, matches it to a Lua script, and executes the script in a new goroutine

func (*LuaExecutor) Stop

func (se *LuaExecutor) Stop()

Stop gracefully shuts down the ScriptExecutor and stops watching for messages
