generated enum types mismatch when imported

[schphil]

When generating rust code for DSRC-region.asn the enums types are suffixed with _Type.

    use core::borrow::Borrow;
    use lazy_static::lazy_static;
    use rasn::prelude::*;
    #[derive(Debug, Clone, PartialEq)]
    pub enum RegAdvisorySpeed_Type {}
    impl RegAdvisorySpeed_Type {
        pub fn decode<D: Decoder>(
            decoder: &mut D,
            open_type_payload: Option<&Any>,
            identifier: &RegionId,
        ) -> Result<Self, D::Error> {
            match identifier {
                _ => Err(rasn::error::DecodeError::from_kind(
                    rasn::error::DecodeErrorKind::Custom {
                        msg: alloc::format!(
                            "Unknown unique identifier for information object class instance."
                        ),
                    },
                    decoder.codec(),
                )
                .into()),
            }
        }
        pub fn encode<E: Encoder>(
            &self,
            encoder: &mut E,
            identifier: &RegionId,
        ) -> Result<(), E::Error> {
            match (self, identifier) {
                _ => Err(rasn::error::EncodeError::from_kind(
                    rasn::error::EncodeErrorKind::Custom {
                        msg: alloc::format!(
                            "Unknown unique identifier for information object class instance."
                        ),
                    },
                    encoder.codec(),
                )
                .into()),
            }
        }
    }

However when imported in DRSC.asn the suffix misses:

pub mod etsi__its__dsrc {
   extern crate alloc;
   use super::super::etsi_its_cdd::etsi__its__cdd::{Iso3833VehicleType, Latitude, Longitude, StationID};
   use super::etsi__its__dsrc__region::{
       RegAdvisorySpeed, RegComputedLane, RegConnectionManeuverAssist, RegGenericLane,
       RegIntersectionGeometry, RegIntersectionState, RegLaneAttributes, RegLaneDataAttribute,
       RegMapData, RegMovementEvent, RegMovementState, RegNodeAttributeSetXY,
       RegNodeOffsetPointXY, RegPosition3D, RegRTCMcorrections, RegRequestorDescription,
       RegRequestorType, RegRestrictionUserType, RegRoadSegment, RegSPAT, RegSignalControlZone,
       RegSignalRequest, RegSignalRequestMessage, RegSignalRequestPackage, RegSignalStatus,
       RegSignalStatusMessage, RegSignalStatusPackage,
   };
