Recently when looking for a way to provide more of our engineers an opportunity to develop and hone their Rust skills and hit on the idea of rewriting the agent simulator in Rust. Not only that, we decided to develop it in the open.
Actix is an actor framework for developing concurrent applications built on top of the Tokio asynchronous runtime. It allows multiple actors to run on a single thread, but also allows actors to run on multiple threads via Arbiters. Actors can communicate with each other by sequentially exchanging typed messages.
For these reasons, a very long time ago, we developed an SNMP agent simulator. We used Java because it was our go-to language at the time. Cut to today, and while we still do most of our server-side work in Java and Kotlin, we also have a growing number of teams developing products for our clients in Rust.
The UdpFramed constructor must be supplied by an instance of a codec object, which implements the Encoder and Decoder Tokio crate traits. It’s used on top of the socket to handle frames. SnmpCodec is used to decode the received UDP socket data into a stream of SNMP messages, and to encode the SNMP messages into ASN.1 encoded UDP socket data. The SnmpCodec is a wrapper of rasn ASN.1 codec framework, which implements the Encoder and Decoder traits to encode and decode UDP frames. The decoder and encoder implementations leverage the rasn ASN.1 codec framework.
