Actor methods
Actor methods are declared inside an actor with def.
An actor method runs in the context of that actor and can access its private state.
An actor method is like a normal method with one extra idea: it runs
inside an actor that owns its own state and message flow. That is why a
method like compute can use secret without
receiving it as an argument each time.
Local actor methods can call each other by name. Methods on other actors are called through that actor's reference.
Because actors are sequential, local function calls and local method calls run one step at a time inside that actor. Concurrency appears when actors call each other. Whether a remote call is sync or async changes ordering and waiting behavior, not just syntax.
def multiply(a, b):
return a * b
actor main(env):
var secret = 42
def compute(a):
return multiply(a, secret)
result = compute(3)
print("Result:", result)
env.exit(0)
Actor methods are public by default. Calls to other actors can be synchronous or asynchronous.
