A New ASN.1 API for Python
There is also rasn library for Rust that now supports most of the codecs (BER/CER/DER/PER/APER/OER/COER/JER/XER).
Disclaimer: I have contributed a lot recently. OER codec (modern flair of ASN.1) is extremely optimized (almost as much as it can be with safe Rust and without CPU specific stuff). I am still working with benchmarking results, which I plan to share in close future. But it starts to be the fastest there is in open-source world. It is also faster than Google's Protobuf libraries or any Protobuf library in Rust. (naive comparison, no reflection support). Hopefully other codecs could be optimized too.

An Open Source Rust SNMP Simulator
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.

Fq: Jq for Binary Formats
Shameless plug, but you may be interested in my library (which is MIT/Apache-2.0) that offers decoding from BER/DER/CER all from a single model in code, there's no UPER/APER support at the moment, but it's coming in the next few months. :)

Rasn 0.4 — New Compile-Time Validation, SET and ANY support, new LDAP and PKIX crates, and more!
Hello everyone, I'm proud to announce the 0.4.0 of rasn! rasn is a #[no_std] codec framework for the ASN.1 data model and encoding rules. Allowing you to safely and easily parse ASN.1 data formats such as BER, CER, and DER in safe Rust. This release focused on rounding out the support for data types needed for more complicated specifications such as PKIX. If anyone has any questions about this release or rasn feel free to ask me here, or on the GitHub Discussions board.

ASN.1 & Serde: Which crate does the community recommend?
For ASN.1 I generally recommend rasn, which does not use serde since that is a poor fit for ASN.1. It went through an in-depth design phase and is currently the most complete and easy-to-use ASN.1 crate I'm aware of.
