Struct der::Any

pub struct Any<'a> { /* private fields */ }

ASN.1 ANY: represents any explicitly tagged ASN.1 value.

Technically ANY hasn’t been a recommended part of ASN.1 since the X.209 revision from 1988. It was deprecated and replaced by Information Object Classes in X.680 in 1994, and X.690 no longer refers to it whatsoever.

Nevertheless, this crate defines an Any type as it remains a familiar and useful concept which is still extensively used in things like PKI-related RFCs.
