11 months ago FYI, I changed 18-e2sm.rs to contain this in order to test:
#![allow(dead_code, unreachable_patterns, non_camel_case_types)]
mod e2sm {
include!(concat!(env!("OUT_DIR"), "/e2sm.rs"));
}
fn main() {
use asn1_codecs::{aper::AperCodec, PerCodecData};
eprintln!("E2SM");
env_logger::init();
// This will break
let decode_str = "080000000100000000002043514901200000";
// This one works if it is uncommented
//let decode_str = "08000000010000000000204351490120000000";
let decode_hex = hex::decode(decode_str).unwrap();
let mut codec_data = PerCodecData::from_slice_aper(&decode_hex);
let e2sm_kpmv3_pdu = e2sm::E2SM_KPM_IndicationMessage::aper_decode(&mut codec_data);
eprintln!("e2sm_kpmv3_pdu: {:#?}", e2sm_kpmv3_pdu.unwrap());
}It is possible that things won't work on master because the untested REAL support that I added isn't working. But in a separate project, I have commented out all REAL values from the KPM spec and regenerated the code, and I see the same errors that I see with my REAL support added. The REAL support does not seem to affect this particular message in terms of changing the length of enum values or anything like that.

When deserializing at a sequence prelude, the code currently seems to assume that extension fields will be present when looking at optional flags. If the serialization code doesn't include the extension fields, then this will result in an error.
As an example, consider the following sequence: https://github.com/gabhijit/hampi/blob/master/examples/specs/e2sm/E2SM-KPM.asn#L55
There are 24 optional fields, but 3 of them are extension fields. The deserializer will fail if not all of the fields are present, with the following message:
Here is an example serialized
E2SM-KPM-IndicationMessagethat does not include the extension fields:You can add fake serialized extension fields by appending another
00to the end of the message, and then deserialization will work fine.
