Lua Actor

Use LuaActor to integrate Lua scripts to your system with actor model.

Message

In actor model, actors communicate with messages. LuaMessage is the only message type accepted by LuaActor:

• LuaMessage can be converted to/from primitive types with LuaMessage::from().
• Lua types(e.g. number, table) will be convert to LuaMessage automatically.

Lua API

Note: Avoid declaring global variables in your Lua script. It might conflict with future actix-lua update and break your program.

ctx.msg

ctx.notify(msg)
