openAmbiguity around Ractor message sending FIFO semantics
Status:
Open
Assignee:

Description
The docs should explicitly state the semantics/properties of Ractor message, especially when it comes to FIFO.
For example, assume I have two Ractors, Ractor A and Ractor B. Ractor A sends two messages "hello"
and "world"
in this order to Ractor B.
If I call Ractor.receive
on Ractor B, am I guaranteed to see "hello"
and then "world"
or is it possible the messages are delivered out of order?

The messages in that case would be guaranteed to be received in order (first "hello" then "world").
If you have 2 different ractors or 2 different threads both receiving messages from the same ractor, then there is no guarantee of the order.
