DerDecoder

@ExperimentalSerializationApi

class DerDecoder : AbstractDecoder, DerDecoder(source)

ASN.1 DER decoder used by Der format operations.

This decoder supports:

annotation-driven implicit tag override processing via at.asitplus.awesn1.serialization.Asn1Tag
sealed CHOICE decoding via sealed polymorphism
runtime ambiguity checks for nullable/optional class layouts
lossless Kotlin Set decoding by rejecting duplicate elements instead of silently collapsing them
