Rust ASN.1 Codecs Benchmark

This project aims to benchmark existing ASN1 PER (Packed Encoding Rules) codecs in Rust.

Codecs used in comparision

The project currently includes the following UPER codecs:

1. rasn v0.20.1
2. asn1-codecs v0.7.0
3. asn1rs v0.3.1

Benchmark Results

System configuration: Ubuntu 24.04, Rustc: 1.81, AMD Ryzen 5850U 32GB RAM.

Encoding and decoding nested SEQUENCE-OF (1000 elements, 5 bytes each)

For more details regarding ASN1 definition, refer to sample.asn

Codec	Encoding (µs)	Decoding (µs)
rasn	1387	165
asn1-codecs	132	49
asn1rs	70	68

Encoding flat SEQUENCE-OF 1000 integers (u64)

Codec	Encoding (µs)
rasn	448
asn1-codecs	53
asn1rs	35

Usage

To run the benchmarks, follow these steps:

cargo build
cargo bench
