== Background An actor is a computational entity that, in response to a message it receives, can concurrently:

1. send a finite number of messages to other actors;
2. create a finite number of new actors;
3. designate the behavior to be used for the next message it receives.

== Behavior Behaviors are executed in the context of an actor's continuation for a specific message.

== Network All numbers are in network byte order (i.e. big endian). See https://tools.ietf.org/html/draft-newman-network-byte-order-01

== Grammar ```bnf ::= | ::= | |

== Future work 1. Define how to retrieve fields about a message (like a reference). 1. Pattern match on a message and define named patterns to allow for more readable code. 1. Create a rust-based runtime. 1. Define what a behavior looks like and how to denote a new behavior 1. Define how to create an actor (needs a reference and a behavior).
